Well, I do play a bit, I'm a working singer, I produce a cover band for corporate and convention type events. I used to run the business full-time out of Las Vegas. But, the situation changed and now I mainly fly down to New Orleans or Orlando for gigs and so it's more part-time for now. I don't play enough, but, I do play guitar, I own a few of those. I don't have a piano. I took the Coursera Musicianship class on my laptop using' virtual piano' and my final piece was pretty original for a laptop keyboard:) I break down a lot of arrangements trying to find to find material that's right for the show band. The requirements for that are very specific and surprisingly little material is appropriate. I looked at your notes on your graph, in the states bar and measure mean the same thing, and you stumped me with crotchet, is that Australian you're speaking?
