Introductions

Hi,
here are links to my two Rav Vast drums which I bought from the manufacturer in Perm, Russia. Good people.

With these two drums, I can play all notes equivalent to somewhere on the keyboard - with the exception of anything that contains the F note. I guess that with key changes and substitutions (which I'm yet to learn about) I can create some good chords and melodies. Any help is greatly appreciated.
I'm not a musician, actually, I'm a beginner with some knowledge - aren't we all at some stage? I have a work-related trauma (think PTSD and disassociation, to begin with) which gives me some good benefits such as I have time to play and learn with my drums and I can't make any mistakes. :) I used to play the ukulele a lot but due to memory and concentration difficulties, haven't been able to continue at the same level. I want to learn and be able to play (at least a sense of) all major, minor, seventh and augmented chords, notes and scales. I need to be able to see all the Nashville number names, notes names of all these scales, etc. In particular, I need to HEAR ALL of the above to assist my ability to recognise and remember patterns. I hope Songtrix can help me. Quite a helpful and healing experimental adventure. Cheers, Al from South Australia.
