Part Three of a Series: Four progressive exercises to solidify your ability to hear “do” in any musical situation. Your ability to hear all the tones in the major scale hangs on your ability to hear and then identify the sound of “do”: the “one”, the “tonic”, the “sun” in the musical solar system. In this final episode of three on the topic, you’ll learn an easy exercise, a medium exercise, a difficult one, and an OUCH! level exercise where you sing a pattern that keys your ear to the sound of “do”. As you practice these exercises, you’ll notice “do” popping out at your ear in music you listen to, play, and learn. This video also connects the vocalizing exercises to ways to use Tone Hole levels (“How Close Is Fa”) to challenge your mastery of hearing “do”! Remember to play with your ears!
