I bought a Hohner (German) 364/24 harp in C, years ago, and found that it was tuned differently from any other harp that I owned. I messed wid it for a bit, couldn’t figger it out, and put it away for another time.
Well, that time is now, years later. I’ve got it out, looked it up in one of my harp books, studied it ’til I could figger it out (The book wasn’t really much help.), and now I can play it. True, I need some practice, but I’m gonna play some blues along wid my Uke blues and slide.
It’s tuned similarly to a chromatic, but doesn’t have a button. It’ll play a C scale for two octaves, but one has to bend an F#! It’ll also play two octaves of 2nd position, but one has to find the way to blow and draw through it that’s not too difficult. I plan on using 2nd position mostly.
It was a favorite of some of the old time blues harp players.
