"And, yes, an octave plus a fifth is unusual, but so is a five noter!"

True. I agree with you.

A couple years ago, somebody from the Cecil Sharp House asked for the names of pentatonic songs (those with five notes), and eventually somebody here posted an list of them. I wish I could find that list again.

It occurs to me that such songs would be good when working with people who have been ridiculed and are convinced that they 'can't sing.'

About that MIDI I promised - dentist first, then voting, then the MIDI.
