WEEK EIGHT

TOPIC: INTERVALS

DEFINITION: Interval is the distance in pitch between two notes in music. Interval is also the tonal gap between two notes.The interval in a musical piece is determined by counting from the root note to the top note.For example,in the scale of C major, the root note C is the 1st and the eight note C above is the octave,which is the 8th interval.The notes between the 1st note and the 8th note are included in the counting.

KINDS OF INTERVAL

1. Harmonious interval
2. Melodic interval

HOW TO DETERMINE INTERVALS NUMERICALLY

As stated previously,the interval is determined within a musical piece by counting the notes starting from the root note to the top note. Examples are as follows.

1. C up to E is a 3rd
2. G up to D is a 5th

QUALITIES OF INTERVALS

The five qualified names of interval are as follows.

1. Perfect interval: This is used for unison, 4th, 5th and octave.
2. Major interval: This is used for 2nd, 3rd, 6th and 7th.
3. Minor interval: This is used for 2nd, 3rd, 6th and 7th.
4. Augmented interval: This is used for 2nd, 3rd, 4th and 6th.
5. Diminished interval: This is used for 3rd, 4th, 5th and 7th.
