In music theory, a scale degree is the name of a particular note of a scale in relation to the tonic (the first note in the scale). In tonal scales, the degrees may be identified several ways: Music theory is a field of study that describes the elements of music and includes the development and application of methods for analyzing and composing music, and the interrelationship between the notation of music and performance practice. ... In music, a scale is a set of musical notes in order by pitch, either ascending or descending. ... The tonic is the first note of a musical scale, and in the tonal method of music composition it is extremely important. ...

• the first, second, third, fourth, fifth, sixth, and seventh degrees of the scale;
• by arabic numerals (1,2,3...), sometimes with carets above them (); and
• in English, by the names tonic, supertonic, mediant, subdominant, dominant, submediant, (subtonic or leading tone).

Subtonic is used when the interval between it and the tonic in the upper octave is a whole step; leading tone when that interval is a half step. The second (symbol s) is a unit for time, and one of seven SI base units. ... In music, see the following intervals: Major third Minor third The mediant, and the chord built on the mediant, is often called simply the third, as it is the third degree of the diatonic scale. ... In music, see: Perfect fourth Augmented fourth or tritone The subdominant, and the chord built on the subdominant, is often simply called the fourth as it is the fourth scale degree. ... A fifth may mean any of three things: 1. ... In music, see the intervals: Major sixth minor sixth The submediant, and the chord built on the submediant, is often simply called the sixth as it is the sixth scale degree. ... In music, see the intervals: seventh, musical group Major seventh minor seventh The leading tone or subtonic, and the chord built on the leading tone, is often called simply the seventh as it is the seventh scale degree. ... The tonic is the first note of a musical scale, and in the tonal method of music composition it is extremely important. ... In music or music theory, the supertonic is the second degree of the scale, it is the second note of a diatonic scale. ... For mediant in mathematics, see Mediant (mathematics) In music, the mediant is the third degree of the diatonic scale. ... In music, the subdominant is the technical name for the fourth degree of the scale. ... In music, the dominant is the fifth degree of the scale. ... In music, the submediant is the sixth degree of the scale. ... In music, the subtonic is the lowered seventh degree of the scale, as opposed to the leading tone. ... In music theory, a leading-tone (called the leading-note outside the US) is a note or pitch which resolves or leads to a note one semitone higher or lower, being a lower and upper leading-tone, respectively. ... In music theory, an interval is the distance in pitch between two notes, the lower and higher members of the interval. ... The tonic is the first note of a musical scale, and in the tonal method of music composition it is extremely important. ... In music, an octave (sometimes abbreviated 8ve or 8va) is the interval between one musical note and another with half or double the frequency. ... The musical interval of a major second — also called a whole-tone — is the relationship between the first note (the root or tonic) and the second note in a major scale (and also a minor scale). ... The musical interval of a half step, semitone, or minor second is the relationship between the leading tone and the first note (the root or tonic) in a major scale. ...
