I have a Hornung & Møller Grand Piano
A Yahama Digital Piano
...and several other synthesizers and sound modules
I also have a violin,
2 trumpets,
1 trombone,
a traverse flute,
several recorders in different sizes,
a clarinet,
a bassoon
and a horn
I don't have an organ yet though
And no guitar? Frederik your not a man without a guitar! Hahaha just kidding! However for anyone looking to pick up a fun and fairly easy instrument (that does require lots of practice), I would highly recommend the guitar. Also, don't forgot that the ladies love men with guitars, even if they can't play 'em...
Oh and I have 3 guitars as of now.. I recently had 6, however I gave them a new home at my local music store.. and picked up some nice cash!
