Conversation after my open mic last night with a guitarist in the audience:
Me: (confused look) I'm sorry...?
Guitarist: (examines looper) Well, you're using the DL-4, right? Yeah, I've got the same pedal. But usually it slows down.
Me: (still confused) You're using the sample function?
Me: Well, that doesn't slow down. There's no feedback function on the Line 6.
Guitarist: Yeah, but when I play with a drummer it starts out okay, and then the loop slows down.
Me: Then your drummer's speeding up. Is he playing with a metronome?
Guitarist: No, man, he's a jazz drummer, he's rock solid.
Me: Well, something's off. I mean... Look, do you practice on your own with it?
Me: I don't know what to tell you. The loop needs to be very precise.
Guitarist: Right. I guess so. I love the sound of the pedal, but it keeps slowing down...
If you decide to do what I do, and by all means you should because it's a great way to practice and build a sense of rhythm, learn this well: the loop does not change. It does not slow down. It does not speed up. That is the whole point of a loop. And because it is mindless, the loop is god. It takes time to get used to playing over samples, because they won't react to you the way a regular band does, but it will teach you to be a better listener, and I've noticed that I've gotten much better at maintaining a tempo since I started.
You have to get it right the first time, and then change to fit the loop if necessary. Because the loop will not change to fit you.
I'm willing to bet that drummers and many bassists especially have trouble with this. As the rhythm section of a traditional band, we're used to setting the dynamic--which is great, that's our job in that role. When you play with a loop, your role must, to some extent, become more of a soloist/accompanist. No matter how solid you think you are, the loop does not slow down.
Last night I played Psycho Killer at Stacy's with someone who didn't know the chords or the strum pattern. I was reduced to shouting chords on the fly as I figured them out from the bassline. Combined with the way that I play/sing Psycho Killer, which jacks up the crazy factor about as high as it is possible to go, it was probably a unique experience for us all. I've missed playing the song, and I think it's time to add it to my set. Here's how I'm going to do it.
Psycho Killer, like most Talking Heads songs, is pretty simple in structure. According to band history book This Must Be The Place, the Talking Heads would often build songs by recording themselves jamming, extract inspired parts, and then splice those progressions together. This gives many of their songs a hypnotic repetition, and facilitated the call-and-response work that made Stop Making Sense such an amazing collection of work. Psycho Killer was one of the band's first songs (indeed, it was the first song that Byrne brought to Weymouth and Franz), and is constructed more traditionally. This makes it a more challenging loop from a playing perspective, but somewhat simplifies the arrangement process.
I arrange songs to fit the Four String Riot in three basic ways. The first is to use a single loop for the entire song. Voodoo Funk uses one background loop the whole time, as does my cover of Naive Melody and the Zelda theme. Songs where I'm primarily sampling percussive sounds also use this method, like Closer (with its boom-shhhk drumbeat) and anything by the White Stripes. Most pop music, however, doesn't use just one progression, but alters it at least once (for the chorus) and often twice or more (bridges and more intricate verse structures). For these songs, I try to find a way of bringing the loop in and out as emphasis, and use technique or technology to fill space when the bass is solo. For example, my cover of Island in the Sun loops the verse progression for a very full, cheery sound, and then drops the loop out and replaces it with heavily distorted chords in the chorus. In contrast, We Used To Be Friends has a big chorus loop, and I fill space in the verse by combining the bassline with percussive slaps (oddly enough, that song actually only uses two basic chord shifts, and just swaps them around, but that sounds weird in a loop). The temporary loop method gives me more complex structures to work with, but it's more technically difficult to perform: I have to trigger the DL-4 in and out at the right times, while working my other effects and singing, plus the unaccompanied bass shouldn't sound too empty.
Not that I'm complaining. The challenge is the whole point of this project.
So for my third method, which I haven't really implemented so far, I'm planning on incorporating a little bit of the previous two. The loop will be running the entire song, but creative use of the DL-4's playback options will allow me to cover several chord progressions in one loop. For those who aren't familiar with the pedal, it gives me two special options for loop output. The first is the 1/2 speed switch, which also plays loops at 2x speed if you recorded them while in "slow" mode, and will reverse-play a loop in either speed with a doubletap. These are really cool abilities, but not always useful in a song context (it would honestly be much more helpful if I could speed up or slow down the loop by degrees, but that's neither here nor there).
The second playback option is the Play Once button, which does exactly what it sounds like. If the loop is currently playing, it will stop once it reaches the end instead of repeating as usual. If the Play Once mode has already been activated, pressing it again will restart the loop from the beginning and play it (you guessed it!) once. That sounds very limited (and it is), but in a song like Psycho Killer where the chord progression cycles back on itself several times, it works perfectly. Let me show you how. Here are the lyrics and chords for the first verse/chorus of the song:
A A A A G I canít seem to face up to the facts A A A A G Iím tense and nervous and i canít relax A A A A G I canít sleep ícause my bedís on fire A A A A G Donít touch me Iím a real live wire F G Psycho killer, quíest que cíest A A A A G Fa fa fa fa fa fa fa fa fa far better F G C Run run run run run run run away F G Oh-oh-oh-ooooh
Hopefully you can see that there are two basic patterns there. The first is A-G, and the second is F-G-C (truncated the first time through). They fit together in a predictable way, i.e. pattern two is almost always preceded by at least one repetition of pattern one. I can create a conglomerate loop that sums up the whole song, minus the bridge, by recording patterns one and two combined (A-G-F-G) and restarting it constantly. This does require fudging the very last part of the pattern, but since A and G are both members of the C major scale, I think I can retrigger the loop there and use the live bass to accent the C instead. It'll become a passing note instead of the dominant chord.
Start loop, press Play Once to prime the loop I canít seem to face up to the facts Restart loop with Play Once Iím tense and nervous and i canít relax Restart loop I canít sleep ícause my bedís on fire Restart loop Donít touch me Iím a real live wire Allow loop to continue through G Psycho killer, quíest que cíest Restart loop Fa fa fa fa fa fa fa fa fa far better Allow loop to run through completion, then begin again at the C Run run run run run run run away Allow loop to finish again, restart Oh-oh-oh-ooooh
Add in Byrne's jittery little drum line, complete with slap bass to replace the mid-song bridge and breakdown from the live version, and you have a complete 4SR cover.
