Hi Todd,
How do those high, low, and in-between sounds not qualify as distinct pitches? I guess they're at least distinctly high, low, and so on.
Cymbal sounds do not qualify as distinct pitches because, to be a bit recursive, they are not distinct pitches! What I mean is, if you listen to any cymbal, you won’t hear 1 and only 1 dominant pitch. Compare that to a note on a vibraphone: both are pieces of metal that you strike, but the vibes key plays a distinct, identifiable pitch, and the cymbal sounds a series of frequencies so complicated that our minds don’t find any 1 dominant note.
If cymbals played distinct notes, we’d either change our cymbal setup each time the band changed key, or we’d destroy all musicality in every song.
I’m not spouting opinion so much as describing physics and psychoacoustics.
What are we supposed to call it then? Is there another musical term I am unaware of to refer to changes in pitch in a musical line?
You can call a series of percussive sounds a phrase. Or something. Clearly, you’ve hit the bullseye of the problem here. Because there is no great answer to your question, Keith Carlock etc. have taken to using “melody” as a metaphor to describe percussive phrases. The result was (1) a way to talk about their playing, and (2) a way to confuse the on-line drumming community.
...and? I need you to tell me why you believe the term refers only to tempered (or “distinct”, as you call it) pitch, and what term you would have me use to refer to changes in untempered pitch.
I’m not talking about tempered pitches. A reasonable definition of “pitch” is this: 1 particular audio frequency within hearing range. Doesn’t matter if you can find it on a modern Western keyboard instrument. But you WILL find any pitch on a (fretless) stringed instrument somewhere in the violin-bass range.
It's not a metaphor, it's the correct, literal application of the term— one of them, anyway.
I suspect that if we asked a group of non-drummer musicians what “melody” means, a total of zero would mention anything other than clearly-defined pitches.
At the end of the day, while I can’t play actual melodies on my drums, using “melody” as a metaphor does give me a reasonable way to describe percussive phrasing. So it’s great for communicating among drummers, but probably confusing to non-drummers.
