Music Fundamentals A Balanced Approach

Perfect intervals for the key of A major are shown below, first melodically, then harmonically.

The quality for intervals 2, 3, 6, 7 is major(abbreviated to “M”).

Notice:

• The A major key signature affects the C, F, and G by raising the note half step, resulting in the M3, M6, and
  M7as shown by the arrows above.


• If the appropriate major key signature is applied to a scale, the resulting interval qualities are either perfect
  or major. Always apply the key signature of the lower pitch of an interval.

Exercise 5

Using accidentals, draw each note of a major scale above its tonic note, forming all major and perfect intervals.
In this exercise, do not use a key signature. Write the interval quantity and quality below the notes. If you have
access to a keyboard, play the intervals drawn below. In music of the West, the M2 and M7 are considered to
be dissonant. Do you agree?
