New Fugue (with ostinato) 2.
Okay, so how do you write one of these things for the drumset (or the piano for that matter)?. Here's what I've done. I created a melodic phrase. Then I figured out a number of variations on it, i.e. inversion, retrograde, augmentation, diminution, and stretto. I put it on top of an ostinato. I played it in one voice. Then I played it in another voice and stuck some counterpoint against it. All of that is in my last post. Then (as you can see on this page) I just played the ostinato for a couple of measures. I'll improv over those measures later. Then, at measure five on this page, I wrote the fugal subject in the primary voice as an augmentation. In this case I doubled the note values, so the phrase that previously took only four measures to complete now takes eight. That subject is played entirely with the right hand, so I've started to put some counter point against it with the left hand on the upper staff. You can see where that starts up at measure five. I will continue this process - writing a few bars of ostinato to solo over, then re-introducing the fugal subject in one variation or another and putting some counterpoint against it. At some point I will probably introduce stretto, where one voice will introduce the subject and before it's finished, the other voice will jump in on top of it. Sooner or later all of those empty measures will be filled in but, for now, I will just concentrate on the occurrences of the fugal subject and the counterpoint I Will play against them.
