The composing ranks aren't available because no matter what you do you won't be able to compose this song fully, you'll get most of it in there at r1 but not all, but regardless it will sound good. I chose lyre and flute for this but honestly it's quite flexible. Lyre and Flute sounds the nicest to me but piano by itself is more true to the original song and substituting a ukulele for the flute sounds great as well.
