I understand about tempo, but how do you set a metronome for 3/4 time or something other than 4/4. 4/4 seems to be it's default is since there are 4 beats per measure. Are there metronomes that you can set to change time in the same music piece like in Blackbird. Last question is that a metronome in the background of the song or taps on the guitar?
thx
