I made an account on here just to share this because the Bard Bulletin Board isn't letting me post Jam Sessions at the moment. T_T
Nothing special or anything, but a fun song and I haven't seen any MMLs for it.
For the Lute part, Mandolin and Ukelele are good substitutes. Piano and Harp sound a bit too high pitched compared to the rest, but if you switch out the other instruments it might actually sound very nice.
The Chalumeau part will also sound great on a Tuba.
The Flute part will sound great on a Whistle.
The Ukelele part is the bass part, so most other acoustic string instruments will do (aside from Violin or Cello) but I just prefer the Ukelele sound for bass parts.
