The scale degrees of a heptatonic (7-note) scale can also be named using the terms tonic, supertonic, mediant, subdominant, dominant, submediant, subtonic. If the subtonic is a semitone away from the tonic, then it is usually called the leading-tone (or leading-note); otherwise the leading-tone refers to the raised subtonic.
In music theory, the scale degree is the position of a particular note on a scale [1] relative to the tonic—the first and main note of the scale from which each octave is assumed to begin. Degrees are useful for indicating the size of intervals and chords and whether an interval is major or minor .
A diatonic interval is an interval formed by two notes of a diatonic scale. A chromatic interval is a non-diatonic interval formed by two notes of a chromatic scale. Ascending and descending chromatic scale on C. The table above depicts the 56 diatonic intervals formed by the notes of the C major scale (a diatonic scale). Notice that these ...
The major scale is maximally even. For example, for every generic interval of a second there are only two possible specific intervals: 1 semitone (a minor second) or 2 semitones (a major second). In diatonic set theory a generic interval is the number of scale steps between notes of a collection or scale.
The composer and music theorist George Perle calls the whole-tone scale interval cycle 2, or C2. Since there are only two possible whole-tone-scale positions (that is, the whole-tone scale can be transposed only once), it is either C2 0 or C2 1. For this reason, the whole-tone scale is also maximally even and may be considered a generated ...
Microtonality is the use in music of microtones — intervals smaller than a semitone, also called "microintervals".It may also be extended to include any music using intervals not found in the customary Western tuning of twelve equal intervals per octave.
In other words, it is the interval between two consecutive scale degrees. Any larger interval is called a skip (also called a leap), or disjunct motion. [1] In the diatonic scale, a step is either a minor second (sometimes also called half step) or a major second (sometimes also called whole step), with all intervals of a minor third or larger ...
[2] The major second is the interval that occurs between the first and second degrees of a major scale, the tonic and the supertonic. On a musical keyboard, a major second is the interval between two keys separated by one key, counting white and black keys alike. On a guitar string, it is the interval separated by two frets.
