"Harmonica According to Charlie Musellwhite"
Greetings, Winslow........Two cuts..."Azul para Amparo"; "Tuff" Do you have these cataloged, Sir? What key, what position... Thank you...Tommy Hutch
Charlie is playing in a minor key. The minor scale in 4th position uses the same notes as the major scale in 1st position, so no overblows are needed. However, the home note in 4th position is Draw 3 bent down 2 semitones, which is why you hear Charlie lingering on that bent note during Azul.
People ask high prices for rare items. Doesn't mean they get them. But aim high, and maybe you'l get closer to the target. Maybe someone will be willing to pay $75, or even the full $100. You'll never know if you don't ask.
But if you're buying and don't have money to burn, and you really do want the book, shop around and be patient. Someone else may offer that old space-consuming piece of junk that no-one could possibly want for a much lower price, or you may stumble on it in a used bookstore.
Azul is in 4th position, A minor on a C harp.
Tuff is second position, D on a G harp.
Charlie doesn't switch harps and positions during the tunes, either, maybe because these were originally instructional recordings.
