Sabbatical: Week 6 Update

It has been quite a productive week. I was able to record 17 phrases on pedal steel guitar. I recorded two each for A300, 727, DC-10, DC-9, & 747. I recorded three phrases for DC-8 and 707. I also recorded a phrase for the center section of 737. On Saturday I booked Alumni Hall to record some piano tracks on the Yamaha C7 grand in that space. All in all I managed to record 10 phrases, two each for TriStar, 737, A300, 727, and DC-10.

Last week I explained some of the basics of how a pedal steel guitar works. This week I’ll go into a little more detail. The second movement of Rotate, 737, is nominally in F major. In the center section of the piece I decided to use 3 seventh chords: an F major seventh, a D minor seventh, and an A dominant seventh. Let’s investigate how you can do this on a pedal steel guitar. This will allow us to review what we learned about tuning and the foot pedals from last week.

Above, we see the open strings of an E9 pedal steel guitar. Playing a major seventh chord in this tuning is simple, you simply play strings 2-6 simultaneously (with the low B on the left being string 10). In order to get an F major seventh, then we’d simply play those strings with the steel over where the first fret would be.

There several ways to get a minor seventh chord. Last week I went over how you could use the first two pedals of the instrument to get a chord built on scale degree four or six. Remember that the first pedal changes all of your B strings to C#, and the middle pedal changes all of your G# strings to A. When we press just the first pedal, the E major chord we get from strings 3-6 is now a C# minor chords. Likewise, when we press the first two pedals at the same time, our E major chord is now an A major chord. We are going to use these two pedals to create a D minor seventh chord.

Let’s think about that chord in the context of C major. We could also think of that chord as being an F major chord (a IV chord) with an additional D (scale degree two). We can get a IV chord by using the first two foot pedal. The additional scale degree two we can get from string 7 (F# is scale degree two in E major). Since we are thinking in C major for this chord, we would have to strum strings 3-7 with the first two pedals down, and our steel positioned over where the 8th fret would be (C is 8 half steps above E).

How about our A dominant seventh chord? We found that major seventh chords on a pedal steel guitar are easy. Here’s where the knee levers come into play. Again, there is no standard for how many knee levers a pedal steel guitar has, nor is there a standard configuration. My instrument has three knee levers. They would be labelled LKL, LKR, and RKR. Those abbreviations stand for left knee left, left knee right, and right knee right. Thus, I have two knee levers for my left leg, and one for my right.

While there are no standards, there is some logic used in setups. For instance LKL and LKR on my instrument both affect the E strings. This makes sense because you’d never want to use both levers at the same time, which is important as it is pretty much impossible to move your knee to left and to the right at the same time. On my instrument LKL raises the E strings to F, while LKR lowers the E strings to D#. The final knee lever, RKR, lowers the D string to C# and the D# string to D. Thus, it is this knee lever that allows me to lower the D# to D, which when combined with strings 3-6 gives a dominant seventh chord. So, in order to get an A dominant seventh chord, I would string strings 2-6 with RKR engaged with the steel positioned over where the fifth fret would be (A is 5 half steps above E).

Sabbatical: Week 5 Update

Well, I’m a third of the way into my sabbatical, and the past week has been pretty successful. I’ve finished my fretless bass recordings, and have started recording pedal steel guitar. I recorded phrases for the center sections of seven movements: 737, A300, DC-8, 727, DC-10, DC-9, & 747. The fretless phrases I recorded for 737 and DC-8 replaced recordings I made last week where I wasn’t satisfied with what I played. I’m much happier with the new versions.

In terms of the pedal steel recordings, I’ve only begun to scratch the surface, recording four phrases, two each for TriStar and 737. Pedal steel is a fascinating, but very complicated instrument. I haven’t played it much in past few months, so a significant amount of time was spent tuning the 10 strings, calibrating the tuning for a couple of the foot pedals, and reacquainting myself with the instrument.

A standard pedal steel guitar has 10 strings and uses E9 tuning. This tuning system was developed by a few prominent players, including Buddy Emmons. It is called E9 tuning, as it generally resembles the notes of an E9 chord, though notice that it has both a D natural, and a D#. Notice as well that the top two strings are actually lower in pitch than the third string from the top. One of the things that is fairly convenient about the tuning system is it features four consecutive strings that form a major triad (strings 3 through 6 – with 10 being the lowest string).

In typical pedal steel playing, the players left hand puts a steel on the fretboard. Typically the placement of the steel reflects what key you are in. For instance, in G major, you would place the steel above where the third fret would be, as G is three half steps above E. In order to get other notes (and harmonies) besides those given by the strings, the player typically uses the pedals and knee levers rather than moving the steel.

While there is no standard for pedal and knee lever configurations, most instruments have three pedals, and one or more knee levers. My instrument is an old GFI SM-10 with three pedals, and three knee levers. Since this is sufficiently complicated, I will only explain the two pedals I used in recording this week. The first pedal changes all the B strings to C#s (raising the string a whole step). The second pedal changes all the G# strings to As, raising the string a half step). With these two pedals and using the aforementioned strings that form a major triad (strings 3 through 6), you can get an E major chord, a C# minor chord (using pedal 1), an Esus chord (using pedal 2), or an A major chord (using both pedals 1 & 2). If we were to think of this in terms of E major, this will get us the chords on scale degrees 1, 4, and 6. Pretty clever all in all. Perhaps next week I will go into detail about some of the other pedals and how they can be used.

Sabbatical: Week 4 Update

Last week’s work really set me up for success this week. I managed to record a dozen fretless bass phrases this week. I recorded one phrase for TriStar, 737, DC-8, and 707. I recorded two phrases for A300, 727, DC-10, and DC-9. Accordingly I only have five fretless bass phrases to record for next week. That being said, rather than get a head start on pedal steel guitar recordings, I may add more fretless bass phrases, or re-record some of the phrases I’ve already recorded in order to have more exciting bass parts.

Again, in the interest of having some visual material to share, here’s the string arrangement for DC-8. In the first six measures you can see arpeggiations of a progression in G major: B7, Em7, CM7, Em7, D7, to GM7. The final seven measures shows a static section where the upper voices slowly arpeggiate a D# diminished chord while the cello stays on an E pedal.

Sabbatical: Week 3 Update

This was a productive week. I finished with the bass harmonica, recording phrases for the B sections of 727, DC-10, & DC-9. Thus, I was able to get a head start on recording fretless bass recordings. I was able to record two fretless phrases for each of the following movements: TriStar, 737, DC-8, 707, and 747. I was also productive outside of the recording project, finishing a grant report, a conference presentation, some sound design work, and a conference presentation proposal.

In the interest of having some visual content on the entry I’ve included the score for the string parts for DC-10. In the B section, the beginning of the example, the strings only use the notes G, B, C, D, & F#. In the A section, the strings reduce to only using G & E, ending on harmonics. This will be one of two movements that use tremolo in the string parts.

Sabbatical: Week 2 Update

Week two has not been as productive as I had hoped. Part of that is due to labor day, part is due to a trip to Boston on Tuesday, and part of it is due to a cursed plumbing job that would never end. Finally, on Wednesday, the external hard drive I use for recording started acting quirky, so I went out and bought a new drive, and spent many hours transferring about a terabyte of data to the new drive. I am glad to report that that process went well, and all my data is safe.

Before going through my productivity for the week, a bit of background on the project. The album will consist of nine pieces. Each piece is in ternary form (ABA). The lead guitar the drum machines and the automated synthesizers pretty much play throughout each piece. This material is already fairly thick and robust. For the additional instruments I am recording I plan to have them play one phrase for each section. Since I completed work on the theremin recordings last week that means there will be 27 theremin phrases on the album (3 x 9 = 27).

The reason I was able to complete the theremin recordings last week is I went into my sabbatical having already recorded many theremin and bass harmonica recordings. To complete my bass harmonica recordings I only needed to record seven more phrases. That being said, I only got four phrases recorded this week, so next week will be a light week for bass harmonica, and I will likely get a head start on recording fretless bass next week.

The four recordings I made this week were all for B sections, specifically, for: TriStar, 737, DC-8, and 707. I feel that bass harmonica is an integral part of my sound as Darth Presley. I love the sound of a bass harmonica. In fact, in terms of satisfaction per dollar, my bass harmonica is one of my favorite instruments. That being said, bass harmonicas manufactured in most countries are actually quite expensive. There are, however a few Chinese manufacturers that make budget instruments. The instrument I have is a Swan bass harmonica, which can be purchased for under $200.

Since this is a light week, I’ll comment a bit on the string arrangements. As I stated last week, I finished the string arrangements. Over the long weekend I formatted them on paper, and created parts for each of the four instruments. The recording session is booked for late October. The musicians will be listening to a click through headphones while recording, so I should be able to just drop the recordings into place once they are edited and mixed.

Each of the string arrangements covers the transition from the B section to the return of the A section. For each movement, the number of pitches used in the B section is greater to or equal to the number of pitches used in the A sections. To put it another way, the A sections have a limited number of pitches (as little as one, and no more than six), while the B sections tend to have a much greater variety of pitches (at least three, and as many as nine).

In the interest of leaving the reader with an image to look at for the week, I’ll leave you with the score for the string arrangement of TriStar. All of the string arrangements for Rotate tend to have a similar profile to this movement, that is the pitch tends to go up, and tends to crescendo into the arrival of the final section. In this case, that section uses only the note G.

Sabbatical: Week 1 Update

The first week of my sabbatical went better than I had expected. I managed to record all of the theremin parts I had hoped to, leaving me a week ahead of schedule. All in all I recorded 13 phrases:

1 phrase for Tristar
1 phrase for 737
1 phrase for A300
3 phrases for DC-8
1 phrase for 727
1 phrase for 707
1 phrase for DC-10
2 phrases for DC-9
2 phrases for 747

The majority of these phrases were recorded using a Moog Etherwave Plus to control a Behringer System 55, which is a clone of the Moog modular synthesizer from the early 1970s. A few of the phrases were recorded using the Etherwave Plus to control a small Eurorack synthesizer centered on the 2HP Vowel formant synthesizer and a the Calsynth Monsoon granular synthesizer. One of the tracks was recorded using just the Etherwave Plus, yielding a traditional theremin sound. Below you can see a patch on the system 55 using four oscillators, a low pass filter, and a VCA.

Due to the new tracks, I’ve re-released recordings of TriStar, 737, and 707. As mentioned in my previous post, I had about a month of data loss. I managed to recover the string arrangements I wrote for TriStar, A300, DC-8, & DC-10, and wrote string arrangements for Rotate 737, 727, 707, DC-9. & 747. Thus, all the arrangements are completed. They only need to be formated for printing so I can send them out to the string quartet that will be recording them. Also relevant to the discussion is my left ear is healing nicely. It may not be at 100% yet, but it is getting there.

Given that I am one week ahead in my schedule, I’m revising my schedule thusly . . .

1 Theremin
2 Bass harmonica
3 Bass harmonica
4 Fretless
5 Fretless
6 Pedal Steel
7 Pedal Steel
8 Strings
9 Trombone
10 Trombone
11 Taishogoto
12 Cello
13 Voice
14 Lyricon
15 Modular Synth

Sabbatical

On Monday I officially start my sabbatical. My project is to complete my (as Darth Presley) forthcoming album Rotate. I have already released preliminary versions of: “TriStar,” “737,” “A300,” “707,” and “DC-10.” In the interest of productivity, I’ve created a weekly schedule, and plan to give weekly updates on my work. A semester is approximately 15 weeks long, so for each week I’ve noted what instrument I plan on recording. All but the strings are instruments I will be recording myself. Since I don’t play 15 different instruments, I have assigned the instruments that I want to be the core sound of the album to two weeks, and the lesser “color” instruments each only get one weeks worth of attention. For the strings, I plan on hiring a string quartet in Providence to play some string parts I am writing.

1 Theremin
2 Theremin
3 Bass harmonica
4 Bass harmonica
5 Fretless
6 Fretless
7 Pedal Steel
8 Strings
9 Pedal Steel
10 Trombone
11 Taishogoto
12 Cello
13 Voice
14 Lyricon
15 Modular Synth

I may also choose to sneak in some recording on a piano as well.

Ultimately I reserved the right to alter the schedule. I have some temporary frustrations with the project as my laptop died, and I’ve lost about a month’s worth of data. Fortunately all my recordings are safe as I do that work on an external drive. However, I’m waiting on a replacement laptop. Likewise, I’ve developed an ear infection, so currently my left ear is missing it’s to 3-4k of hearing. I was told it could take two months to fully heal. In the meantime I think I can come up with work arounds for fine tuning the stereo mixes.
