well, I know some neat ocarina solos! Been playing 'em for maybe 18 years or so. Have 'em in size from tweety little things to a baritone..(know a guy who has a bass). These are NOT the store-bought classic ones usually called a 'sweet potato', but clam-shaped or spherical ones made by a local artist.

One of my favorite tunes is MRS. MACDONALD'S LAMENT

Jingle Bells is also easy....
