D Major — In Thirds
Scales harmonised in thirds are a core jazz, classical, and fingerstyle drill — each beat is a two-note voicing of the scale tone plus a diatonic third above. The intervals alternate between major and minor thirds depending on the scale degree.
Tempo120 bpm
Playback sounds an octave below the written notation — the instrument's concert (sounding) pitch.
