Thanks for the advice guys, I'll get practicing. The idea of Cole Porter, Gerschwin or Berlin on the accordion is pretty cool!

However I'm now confused as to what notes exactly comprise a diminished chord... I always thought that (eg in C) you drop the 3rd and the 5th, giving you C, Eb, Gb. But Sorcha says (above) that you _raise_ the top note (the 5th?) and drop the bottom note, presumably giving you C, E(flat?), Ab, B ????, then M.Ted (also above) describes the dim. chord as a series of minor thirds, so it would be C, Eb, Gb, A.

So my understanding is - you drop the 3rd and the 5th and then add a 6th. Is this right? I'm a piano player too, you think that I would know this stuff by now!

Thanks for clarifying! Daisy
