Danny what kind of small changes can you make while the song is playing?
Question: Other than volume on rare occasions what changes do you feel you have to make when the song is playing?
Later,
Danny people want to add a repeat to the song while playing. Go back and add an additional Chorus, verse or bridge and chorus. Skip the ending and return to the beginning of the song. Or stop before playing the last verse or chorus.
In other words rearrange the parts of the song while it is playing, like the leader of a band would do so a soloist could continue their solo until they decide to bring the band back in. (Loop the solo part and take a cue from the soloist or band leader to go back to the rigid framework of the song.)
