While I practice some pieces with metronome, I try to make notes coincide with the metronome clicks as precisely as possible. However, some (most?) classical pieces have tempo changes like fermata or ritenuto, which break the synchronization of my performance with the metronome.
So, when using the metronome, I ignore all tempo changes. This is not too bad, but still I wonder whether there is any way to employ them.
Is it possible? If yes, how?
