A Major — In Thirds
Scales in thirds are a foundational pianist's drill — both hands move in parallel, a diatonic third apart, developing independent finger control while reinforcing the scale's diatonic structure. The harmonic interval between hands alternates between major and minor thirds depending on the scale degree.
