There is an instrument called a handpan that is essentially a small steel drum you can hold on your lap. The appeal for me is that the it makes me think I could play parts of the soundtrack to the film "Solaris" composed by Clint Mansell. The handpan can be made to a specific tuning, just like regular steel drums, I guess, so maybe I could get all the notes played on some songs, like "First Sleep" and "Don't Blow it".

Then, in times of uncertainty, I could sit and play "Don't Blow it" as I ruminate. Fortunately, playing the instrument looks a little silly, which should prevent me from slipping into full-on brooding.
