“Amazing Grace” (Traditional) is one of the folk songs in the Ocarina Bard library. Here’s its tab for the ocarina in The Legend of Zelda: Ocarina of Time on Nintendo Switch: every note shows which button to press (L, R, A, Y or X) and whether to move the stick or the D-pad.
It has 33 notes and uses only buttons and the stick, no D-pad: a great one to start with.
It also has a second voice: turn on duet mode to play it with a friend at the same time.
You can listen to it, change the key and tempo, share it and download it as an image.
