I am looking for some ideas on using a click track for our worship services. Our leader is not the best when starting a song with the right BPM. We were rehearsing a song and I thought it was a little fast so I pulled out my phone and checked it. We were supposed to be at 108 BPM, we were playing it at 138 BPM. I play bass and would be the one to institute using the click. We do about five to six songs a set with varying degrees of BPM and we would need to be able to change on the fly when we transition between songs really quickly. Typically we would end a song on say a large G chord, let it ring for a moment and then start the next song in the same key with a different BPM that would have to be set. Any suggestions for someone whose two hands are pretty busy while playing?
