1st Tone (High-Flat)
Tone Pitch & Cadence: Tone 1 is a high, level pitch maintained flat across the syllable, similar to singing a steady high note or saying 'moth-er' on a high flat key.

Physical Tone Gesture: Hold your flat hand high and steady in the air, moving it in a straight horizontal line to represent the high level pitch of Tone 1.
