I’ve just received a choir piece that contains some (rare) quarter tones on long held notes. For example, a B which slides into a Bᴓ (that's a half flat).
I’ve tried singing the part where it happens. Not for very long, I’ll admit, but with little success. It seems that my brain tends to put the pitch into a category it knows well: either I’m hearing a (low) B, or a (high) B♭. I’m never sure I’m singing the "right"1 note.
How can I ensure that I’m actually singing this "right" note? Do any of you know of some tools out there that could help me train my ear?
- I do realise that "right" here can actually have different meanings. Let's say 24-TET. Quite frankly, if I manage to consistently sing something that is not quite a B, nor quite a B♭, I’ll be satisfied anyway.
