Triads and Scales Degrees

The following table shows the scale degrees where we find each type of triad:

Triad Major Scale Natural Minor Scale Harmonic Minor Scale Melodic Minor Scale

Major I, IV, V III, VI, VII V, VI IV, V

Minor II, III, VI I, IV, V I, IV I, II

Diminished VII II II, VII VI, VII

Augmented - - III III

Triad	Major Scale	Natural Minor Scale	Harmonic Minor Scale	Melodic Minor Scale
Major	I, IV, V	III, VI, VII	V, VI	IV, V
Minor	II, III, VI	I, IV, V	I, IV	I, II
Diminished	VII	II	II, VII	VI, VII
Augmented	-	-	III	III

Knowing the type of triad formed on each scale degree may be very helpful when identifying triads.
