Phenomenal at: Sibelius. I cracked out loads of musical bangers on that in the music technology room at school. £500 per year or something to have at home though 
Can play, terribly: keyboard, piano (did lessons for about 8 years but only completed grade 2. learned the pieces for grade 3 but never ever practised.), voice (we had to do singing assessments in front of our whole classes for 2 years at school - got Cs in the ones I took seriously, but got an A when I took the role of Pumba in a group rendition of Hakuna Matata because I “led the group with energy and enthusiasm”)
Own but can’t play: ukelele, electric guitar - would like to play both but never had lessons and incredibly un-dextrous/musical (I can’t tune either with specific electric tuners for each instrument. one or two of the notes always sounds wrong.)
Will be happy to learn Wonderwall and then give up, I think.
I’m also very good at drumming tabletops with my fingers in an accurate and rhythmic impression of my gerbils having a stamping tantrum.
