NOTE

MUSIC: INTERVALS 

Intervals in music refer to the distance between two pitches. They are measured by counting the number of letter names and the number of lines and spaces between the two notes, including both the starting and ending notes.

Classifications of Intervals

Intervals can be classified into two main categories:

1. Perfect Intervals: These intervals have a very stable and consonant sound. They include the unison (P1), fourth (P4), fifth (P5), and octave (P8).
2. Imperfect Intervals: These intervals have a less stable and more dissonant sound compared to perfect intervals. They include the major second (M2), major third (M3), minor third (m3), major sixth (M6), and minor sixth (m6).

Kinds of Intervals

Intervals are further classified into two types based on their size:

1. Simple Intervals: These are intervals within the octave (from the first note to the eighth note). For example, seconds, thirds, fourths, fifths, sixths, and sevenths.
2. Compound Intervals: These are intervals that extend beyond the octave. They are formed by adding one or more octaves to a simple interval. For example, a ninth, tenth, eleventh, etc.

Types and Inversion of Intervals

Intervals have two types: melodic and harmonic.

1. Melodic Intervals: These are intervals played sequentially, one note after the other.
2. Harmonic Intervals: These are intervals played simultaneously, or together.

Intervals can also be inverted, which means reversing the order of the notes while maintaining their distance. For example, a third becomes a sixth when inverted, a fourth becomes a fifth, and so on. Inversions are classified as:

- Perfect intervals remain perfect when inverted.

- Major intervals become minor when inverted, and vice versa.

- Augmented intervals become diminished when inverted, and vice versa.

EVALUATION: 1. What is the meaning of intervals?

2. Identify and discuss the types of intervals
3. Mention the 2 kinds of intervals
4. Identify the inversions of intervals
