August 2021 Grapevine

It’s time for some summer listening. I like to listen to a lot of music while I’m driving, especially new albums I’ve bought (I still love albums on CD). And even in the summer when I’m listening I like to go ‘windows up’ – wind noise takes away from me hearing everything I want to, especially if it’s something I’m hearing for the first time. Yeah, it’s a bit odd but I’ve never felt the need to worry about my odd behavior. So the theme for this month’s music can be headed under the idea of ‘critical listening’. The idea for this month’s selections and discussion is try to listen to all the different parts of the song. Usually if you’re listening to a song you take in the overall sound. Most people will pick up on the main parts of a song – the vocal, a lead instrument break. Maybe it has a great drum beat. But often it’s the little pieces that you don’t consciously listen to that make a song stick with you. That’s why the arrangement and the mix are so important. And it’s why the arrangement writing and the recording process are such an art. The best sounding songs treat all their parts as equally important as the main parts. You can listen to some songs and hear that the little things were considered ‘throw away’. Those songs may hit you because of a great vocal, but I don’t think they’ll stay with you as long. At least they don’t for me. So here we go……..

First Up: John Hiatt With The Jerry Douglas Band – ‘Long Black Electric Cadillac’

Here’s a great way to start. John Hiatt has been around for a while. His songs have been recorded by countless musicians and he’s known as one of the best song writers around. He teams on this song with Jerry Douglas, another musician in great demand, best known for his dobro resonator and lap steel playing. First, let your ears cruise through the overall song. Great vocal sitting on top and the lyrics are a lot of fun. The song is arranged to highlight the vocal. Now let’s pick apart the rest of the song. Hone in on the double bass. You can hear it keep a steady bottom end, sitting on the bass roots of each chord. This sound stays in the center of the mix. – (I should probably add here that you might miss a lot of this if you’re just listening on your phone or tablet without headphones. Things get lost – especially bass tones). Hiatt is keeping the main strum going on six string acoustic. There’s an electric guitar and violin that hold down regular rhythm parts and come in occasionally with sweet little lead riffs. In the recording arrangement these are panned pretty hard to the left and right side of the mix. Jerry Douglas’s amazing slide work on the resonator often acts as a call and response to the vocal, so it tends to sit relatively in the center of the mix. With everyone doing their part, the rhythm of the entire song just chugs along. And that’s the important and difficult part in putting an arrangement together – everyone has to do their part. All the players have to keep the rhythm going. Even the vocal has a rhythm to it. Catch the nice little break at the 2:12 mark. If the musicians do it right, what do you have? Awesome.

Next Up: Mdou Moctor – ‘Ya Habibti’

I’ve included a Mdou Moctor tune in a Grapevine before. I just bought this album and got to listen to it front to back on a drive. Tuareg guitar music, sometimes called desert blues, presents a whole different type of rhythm. If you haven’t heard it before, the feel is bit more exotic than most music you’ll hear on American radio. Even though Moctor is known for his amazing guitar work, the musical arrangement is more drum based. The instrumental lineup would be familiar – kit drums, bass, rhythm guitar and lead guitar. The rhythms and scales played give the music it’s different feel. The drums and rhythm guitar stay on a pattern that drives the song along. The bass is not as prominent, but listen closely and you can pick it out. The bass and the guitar sounds usually keep to higher end frequencies, so you don’t have as deep a bottom end. Another sound that drives this song is traditional rhythm instruments as well as handclaps that are added in. You can hear them panned to left and right along with multiple layers of vocals that give the recording width and fills in the stereo sound. Take some time and listen carefully. See if you pick out the string sound on the rhythm guitar and some of the tom fills on the kit drums (hear some nice tom fills at the 3:07 mark). On this song Moctor keeps his guitar playing to quick, repeating passes. If you look online you can find some live performances where the guitar work absolutely shreds. I’d love to have this album on a long drive on an empty two lane road out in the desert.

Finally: Black Midi – ‘Dethroned’

We’re moving on to something with a very different feel. How would you describe the music of ‘Dethroned’ by Black Midi? I’m not sure there’s a perfect description and my take on descriptions is ‘why bother’. In the beginning of the song the drums have a very prominent presence in the mix. They set the tone for what is to come. The beat is not really straight forward, but if you listen you can hear how they work around a count. A guitar comes in when the vocals do and that guitar in the beginning keeps a very straight count. It’s placed slightly to one side of the mix. Vocals have a big presence, but they mute that slightly by drowning them in reverb. By the minute and a half mark the bass is in adding a deep background and the guitar sound is starting to expand. Listen to the repeating riff the bass is playing. It’s probably the most straight forward line in the first half of the song and really keeps the guitar and drums grounded. At the 2:30 mark the drums and guitar turn to more simplistic lines. By three minutes a second guitar line is added and the guitars spread out in the stereo mix to left and right side. By the 4:00 minute mark things get a bit chaotic. The guitars have now taken over prominence in the mix with the drums dropping back a bit. The song rolls to the end in this fashion. I put this song in because it’s a great example of how a band can chart out a song arrangement from beginning to end and how the prominence and stereo placement of each instrument in the mix determines the song’s journey. If they had kept one sound and placement of instruments throughout the song it would not be nearly as interesting and engaging.

Retro: Alice Cooper Band – ‘School’s Out’

There can be a lot of reasons a song remains memorable. In rock songs one reason can be an unforgettable guitar riff. (That’s one reason I still love listening to Led Zeppelin – riff rock at it’s finest.) The guitar riff in ‘School’s Out’ has to be one of the most memorable of all time. Just play the first 20 seconds of this song and most people will immediately name the song, before a single vocal line. But like a lot of music from that era the other part of the recording that pulls me in is the clarity and placement of each instrument. Listen to the prominence of the bass line in this recording. It’s really another great riff that weaves around and enhances the guitar line. The main guitar is placed in right side stereo and the rhythm guitar, playing lower fuzz tone chords is on the left side. The drums are really crisp. And the vocal sits on top, nice and clear so you can take in the lyrics. In the lead guitar part of the song, they put a guitar playing the original riff in the right side stereo and the rhythm guitar in the left channel while the lead takes a vocal space in the middle of the track. It’s a fine line keeping the instruments in a higher crisp frequency without pushing them too far up where the sound just becomes annoying. Recorded and mixed correctly, this song becomes a classic. Without the correct mix and arrangement the song could end up in the bargain bin. Another point to remember is that in 1972 when this came out, most people heard songs for the first time on the radio. The frequencies and clarity were really important to cut through on radio. Sit back and enjoy this classic summer song.

In The Studio Ep 13 – Recording Electric Bass Guitar

Episode 13 of our In The Studio series discusses how to record electric bass guitar. When you’re listening to the video, there are a few places where we give sonic examples of the different methods. All of this video was recorded directly to the GoPro camera, including the sound. The ‘amp sound’ is a live amp in the room. The ‘direct sound’ is being heard live in the room through the studio monitors. As a result, the differences in sound you hear on the video aren’t as great as they would be if you heard them after were tracked in the recording system and played back. Keep this in mind if you’re listening and trying to decide what type of sound you might want. Also remember you can do more processing on the sound after it is captured – either before or after mixing. As always, questions and comments are welcome.

Follow The Chain

When we did our last video for In The Studio we discussed the basics of microphones. Part of that discussion was that microphones were one of the entry points for inputting and capturing sound in your system. Today I thought we’d do a post discussing two of the next steps of ‘the chain’ (really two possible options for the next step of sound capture). My usual next step for capturing sound from a microphone would be to run them in to an outboard microphone pre-amp and then in to an outboard compressor. This is my personal choice as my mixing boards have inboard mic-pre-amps and compressors that could also be used. Again, we’re going to discuss this in relatively non-technical terms so anyone can have a basic idea of what the equipment does. I’m also not recommending specific brands or models. They all have their strengths and weaknesses and that’s a whole separate discussion.

Let’s start with the mic pre-amps. The simple explanation of a mic pre-amp is that it increases the signal from the microphone so that you have enough signal volume to get a good sounding recording. Let’s look at the pre-amp below:

This is a two channel unit so we’re only looking at one side. First, it has a button to activate phantom power. As we discussed with microphones, condenser mics put out less voltage than dynamic mics, so we need to use phantom power to add that voltage. If you use a separate phantom power unit in line before the pre-amp, you won’t need to activate this. The pre-amp has a dial where you will determine the volume added to the signal going in to the unit (Input) and a dial for adding volume to the signal leaving the unit (Output). The amount of power added to the input is measured by the LED lights at the bottom right and the output power is measured by the needle display in the upper right. You also have a button labeled ‘Gain’ where you can boost the input signal by another 20 decibels. You have a button to reverse the signal phase (if you want to know about signal phase, dig in our archives for the video on recording a snare and phase cancellation). The ‘HPF’ button is a high pass filter. You can use this to ‘roll off’ at a certain frequency – we’ll save a deeper explanation for another time.

This mic pre-amp is a little more high end and allows you to be a bit more specific in adding signal to certain frequencies. These are the toggle switches and dials to the right in the photo. Other than that, the mic-pre works in the same fashion.

After the mic pre-amp, the signal is sent to a compressor. The basic function of a compressor is to regulate the volume peaks of the signal before it moves to the next step. This can keep the signal from ‘clipping’ and adding audible ‘pops’ to the track if a volume peak is too loud. Let’s take a look at one and go through it’s options.

Going left to right. ‘Threshold’ determines at what volume the compressor takes hold of the signal. The ‘Ratio’ determines what the unit does with the volume once it reaches the Threshold. If you select a Ratio of 4:1 it means that once the volume level hits the Threshold, the compressor will allow the output to increase by 1 decibel for every 4 decibels of actual volume. The ‘Attack’ determines how quickly the compressor applies the Ratio and ‘Release’ determines how quickly it stops applying the Ratio when the signal drops below the Threshold. When you apply compression to a signal, you will reduce the overall top volume. The Output dial allows you to make up for this by increasing the overall output from the unit. Finally, this unit also has a ‘Gate’. The Gate allows you to select how much volume is needed to allow the signal to pass through. For instance, when you are recording a vocal, you don’t want anything from the mic to pass through when the vocalist is not singing. You would be picking up unwanted background noise. The Gate shuts off the signal when there is not enough volume going in to the mic. The ‘Rate’ dial allows you to adjust how quickly the gate takes effect.

The compressor in this photo also has a limiter (far right), which means that beyond applying the Ratio, you can set the compressor to cut off the output signal totally at a certain level.

Above and beyond controlling the signal level, mic pre-amps and compressors are used to add color, depth and tone to the signal you are putting through them. Mic pre-amps can use tubes or solid state circuits to accomplish their goal. They can run from affordable to incredibly expensive. Each type will add their own flavor to the sound you are recording. Compressors have been used as an effect to give certain sonic qualities to an instrument – you can find lots of info about using heavy compression on snare and kick drums to achieve a specific sound. Compression can be added at many stages of the recording process. You can add compression to tracks already recorded in the software. You will usually add compression to the final mix to even out the overall volume of the music.

We’ll continue to move through the recording chain in future posts. As always, let us know if you have questions or comments.

Messin With The Music Part 9 – Seven Nation Army

We’re back with another ‘messed’ song for your enjoyment. There’s a bit of a story with this one. ‘Seven Nation Army’ was actually recorded before most of the other songs that have been posted. Recording these covers did start with one idea we have maintained with all the songs – recording the tracks straight through to keep it having a more ‘live’ feel. With this song we did what we often do with our own studio songs – record multiple tracks of each instrument for a more ‘full’ sound. So most of the instruments on ‘Seven Nation Army’ were tracked several times (although each separate track is recorded straight through). We also used multiple mics on the acoustic instruments, adding even more tracks.

This tune has twelve string guitar, mandolin, banjo and six string guitar. The percussion is the floor tom from our drum kit and a shaker. Each instrument was tracked several times (except the percussion). Two more mandolin parts were added in the one instrumental section as a ‘lead’ instrument. When we finished recording I realized it would take a while to mix correctly so we decided to record another song without all the multi tracking and multiple mics. And when we finished that song we thought of another, then another……… So it took quite a while to get back to mixing ‘Seven Nation Army’.

As we continue messin’ with songs I’m sure more electric instrumentation while come in to play along with a bunch of other ideas. As always, hit us up with comments and questions if you have any. Hope you enjoy.

Messin With The Music Part 5 – Novocaine For The Soul

Greetings. We’re back with another tune to be messed with. This time we’re honoring ‘Novocaine For The Soul’ by Eels. This was a fun song to work with. I really enjoy the anthemic, sing along nature of the song. Again, we stayed basically acoustic except for the bass guitar. The song has 12 string guitar, bass, mandolin, six string banjo and a little percussion with tambourine and egg shaker.

To give a wider, stereo feel the 12 string guitar foundation track was played twice and panned hard stereo left and right. I think giving a track a wide stereo sound is important and playing a duplicate instrument track is a great way to do it. The two tracks can be very similar, but will almost never be identical (unless you force that with computer manipulation) so you hear each track distinctly from each channel. We worked the same concept with the vocal tracks, recording the main vocal twice and adding two harmony tracks.

Another thing that made this song interesting was the key. We don’t usually change the song from the original key. Specific keys do give songs a certain feel. Major key versus minor key or in this case having the song in D flat instead of D. In the original song they did this by using capos on the guitars. We ended up down tuning the 12 string guitar a half note and transposing the chords so the guitar could be played in first position for a fuller, richer sound. A capo was used on the 6 string banjo. We also added a second mandolin track that acts as a ‘voice’, along the lines of playing a guitar lead.

We may not have said this before, but all the Messin’ songs are played by Electrostatic Rhythm Pigs. You can find these songs and the band’s original music on our SoundCloud account (we have links on this site). We’re also slowly adding all the band’s songs to our YouTube channel (here’s a link to our YouTube channel): https://www.youtube.com/channel/UC0vVN4p_KzvLg1DEuUSJoqw

In The Studio – Episode 8

Welcome to Episode 8 in the ‘In The Studio’ series. Today’s topic is how to create mixing options for yourself during the recording process. A couple things to add about the process in the video. In the video the guitar sounds you hear have not been EQ’d on the mixing board. You can magnify the differences in sound by tweaking the EQ on each microphone using the mixing board. You can also add more diversity by adding effects units in the line between the guitar and amp (this will make more sense after you watch the video). As always if you have any questions or ideas, let us know.

Sound And Vision Leaves Your Head Spinning

Music tech advances as fast as you can blink. Check out this video from Beck covering David Bowie’s ‘Sound And Vision’. The interpretation is cool enough, but the tech behind it is remarkable. It’s the recreation of a 360 degree immersive environment using state of the art recording and an old but not that well known recording technique called binaural recording. Binaural is very different from stereo recording because it takes in to consideration the natural way a human head hears sound. The Sound and Vision project takes your ears in to that natural recording space as well as letting you travel through the video visually. You can now be in the concert space without leaving your home. It won’t be able to replace the full body experience of live music, but boy are they getting close.

Here’s the video:

I’ve also included an article discussing the tech involved:
