Intervals in music are important for understanding the sounds of chords and dyads. Even melodies can benefit from a clear understanding of intervals. Unfortunately, a lot of the information I have found out there is confusing. I’m trying to unravel it for myself and you may get something out of it as well.
Some of what makes Boards of Canada’s songs (or for that matter, any artist’s songs) interesting for me are the chords. If you know the chords, you can get a feel for how to make your own song sound similar or “in the flavor of” so to speak. From the chords, you can often get a melody you like by building off of them or playing along with them. You can even arpeggiate them.
I took the chords from Boards of Canada songs and put them into Xfer Records Cthulhu. From Cthulhu, you can make variations, add low notes, and change to major/minor/suspended. This gives a lot of inspiring chord progressions from some of my favorite Boards of Canada songs. I put them into a zip file of chord presets that you can use in Cthulhu for yourself (see below).
Modes can add interest and really shape a musical piece so knowing the modes and what each is noted for is a good thing. I come back to this post quite often when I am composing so I can choose a mode.
