First an audio clip below, and then some keyboard harmonica modification tips in a future post.
Here is a 45 second clip of a keyboard harmonica blues solo using a slightly modified Hohner Piano 26 and a special trick I will reveal later in an upcoming post. Not quite a harmonica, but very expressive and I think just as cool.
The old Hohner cassottos have a characteristic sound with harmonica overtones, and they have their place, but I have found over the last year that they are not as expressive nor as powerful as the regular Hohner Piano 26/27/32 series of melodicas, at least plying them the way I play them.
By the way, the recording was just an informal pocket recorder recording of me and two band mates rehearsing last week.
