Intervals

WHAT’S AN INTERVAL?

An interval is the distance between pitches. Intervals have a number and a prefix. The number represents the number of pitch names (C,D,E,F,G,A,B,C) from the first to the second pitch. It also indicates how many lines and spaces of the staff are between the pitches (including the pitches themselves). For example, the whole step C to D contains two pitch names, C and D. This interval is called a second. The interval from C to E contains C, D and E; three pitches. This interval is therefore called a third.

The trend continues through to the interval containing eight pitch names. An interval containing eight pitch positions (from C to C or from G to G) is called an octave. An interval from one pitch to the exact same pitch is called Unison. The diagram below shows a C major scale. The intervals are marked.

The second part of an interval name is based on the quality of the interval. It is referred to as the prefix.

Perfect intervals include the unison and the octave. Perfect intervals also include fourths and fifths. Perfect intervals are labeled with a capital “P.”

The Major prefix is only used for seconds, thirds, sixths and sevenths. Major intervals are labeled with a large “M.”

Minor intervals occur when a major interval is made one half step smaller. This can be done by raising the bottom note or lowering the top note. Minor intervals are labeled with a small “m.”

IDENTIFYING INTERVALS

The easiest way to find an interval’s name is to first, count all the pitch names present (or the lines and spaces) including the notes themselves. To find what type of interval it is, what number does it have?  1, 4, 5 or 8 is Perfect.  2, 6 or 7 is Major (or minor if the note is sharp or flat)

Intervals are traditionally considered either consonant or dissonant. Consonant intervals are usually described as pleasant and agreeable. Dissonant intervals are those that cause tension and desire to be resolved to consonant intervals. These descriptions relate to harmonious intervals.
