I am a woodworker who is trying to reproduce a barrel organ that was
first built in the 1500s.  As mentioned above, I am a woodworker who
knows very little about music.

I am hoping that someone out there can help me determine the size
of the pins and how they should be placed on the barrel (wood pins
were used at that time) to produce an approximate 3-minute song using
10 organ pipes.  The barrel will be approximately 40" in diameter.

The barrel will be made to suite the music so this is approximate only.
The barrel should make one revolution to play this song, with no other
songs on the barrel.

First, can a computer program somehow be used to assist in transferring
music notes to the placement of the pins?

Second, if this cannot be done, can someone help me take a song that
was popular during the renaissance period and by hand develop a roll
of paper that I could place around the barrel and, so to speak,
"copy" the music to the barrel?

Other methods?
Kind Regards,
Joe Husbands
