Sheet Music Germany

Hohner Club Ib Accordion?
I recently picked up a used Hohner Club IB Accordion. When I looked in the case, there was sheet music, and from what I can tell, the music dates back to Germany between 1912 and the 1930′s.
Does anyone know anything about these instruments, and more importantly, does anyone know where to find information about playing them? I found a finger chart, and that’s as far as I got. It has 8 bass buttons, and 30 treble buttons. I think it’s in the key of C/F.
What you have is called a diatonic accordion. The club models had the third row of “helper” notes to allow playing in other keys.
Assuming you have a C/F instrument-
The outside row is called the “home row” and is in the key of C
The middle row is called the “companion row”
The inside row is the “helper row” and plays notes that are not in the C or F scale
If you have a finger chart of the notes (and can read music) you have all you need to begin playing. Looking at the chart, the fourth button from the top on “push” will be the root note of each row (C & F). From there a scale can be played moving down the row in the sequence – push(c) – pull(d) – (next button)push(e) – pull(f) – (next button)push(g) – pull(a) – (next button)PULL(b) – push(c).
Searching for “diatonic accordion lessons” on youtube should yield some results.
Good luck.
