I seem to recall that diatonic scale played on a ten hole, Blow, draw, blow draw, blow draw, draw blow occurs from holes 4 through 7. Don't apply that to holes 1-3 or 8-10, it won't work. Tony "Littile Son" Glover did a great Blues Primer for the Hohner company which used to accompany the Blues Harps which laid it all down. The world of 10 hole harp has come a LONG way and there's lots of info available as well as "kinds" of harps to cloose from. Tj
