I play:

-piano (took lessons starting at age 8, only stayed for a few years, but I still play to this day)

-guitar (a little bit of everything, i'll play popular stuff and lately i'm learning classical and flamenco on acoustic)

-Viola (well I only played it for 5th and 6th grade, but I thought I'd add it to the list)

-Violin (switched to it after viola, I don't really play anymore though)

-Mandolin (it's the same strings as the violin basically so one day I just started playing my dad's mandolin and was like, hey, this is the same! )
