macronome
A macronome is like a metronome having a bad day and only giving you four ticks before it throws a tantrum.
My drum set teacher said my timing was a macronome. I said I’d rather play with a broken snare.
I did a macronome in the middle of a test. The teacher gave me a D and a lecture.
I tried to use a macronome during a solo. It failed. I failed.
