Begin by locating G on your instrument and play through the 5 notes of the Iwato scale slowly, ensuring each note rings clearly before increasing speed.
The G Iwato scale contains 2 flats (Ab, Db). This scale does not follow a traditional major or minor key signature, so reading from sheet music may require accidentals.
Practice Routine
Begin by playing the G Iwato scale ascending and descending at 80 BPM using a metronome, one note per beat. Once comfortable, practice in thirds (G-C, Ab-Db) to build intervallic familiarity. Spend 5 minutes daily on this pattern before increasing tempo by 10 BPM.
