My Hat It Has Three Corners: a traditional children’s song and musical brain teaser. Usually repeated five times, with single movements accompanying each word. See game instructions in Mama Lisa’s World Blog. Original melody from the folk tune Carnival of Venice (See italian version in Luiraffimarti.it). German version: Mein Hut Der Hat Drei Ecken.
Played in unison, this melody let us study the C major scale and the thumb passage:
My hat it has three corners,
three corners has my hat.
And had it not three corners,
it would not be my hat.
