Have you ever heard a cuckoo bird call "cuckoo!" from a clock, or called "yoo-hoo!" across the playground?
Those famous calls use just two musical notes: a higher note called sol and a lower note called mi.
How do our voices know which note to sing?

High Sol and Low Mi

In music, pitch means how high or low a sound is.
Sol is our higher pitch note, and mi is our lower pitch note.
Can our hands help our voices sing the right pitch?

Secret Hand Signs

Musicians use hand signs to show their voices where to go.
For sol, hold your hand flat near your shoulders with your palm facing toward your face. For mi, turn your flat hand so your palm faces down toward the floor near your tummy.
