In music, the subtonic is the degree of a musical scale which is a whole step below the tonic note. In a major key , it is a lowered, or flattened, seventh scale degree ( ♭ ). It appears as the seventh scale degree in the natural minor and descending melodic minor scales but not in the major scale .
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.
In music theory, Roman numeral analysis is a type of harmonic analysis in which chords are represented by Roman numerals, which encode the chord's degree and harmonic function within a given musical key. Specific notation conventions vary: some theorists use uppercase numerals (e.g.
As a diatonic function, the leading tone is the seventh scale degree of any diatonic scale when the distance between it and the tonic is a single semitone.In diatonic scales in which there is a whole tone between the seventh scale degree and the tonic, such as the Mixolydian mode, the seventh degree is called the 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. Also commonly used is the (movable do) solfège naming convention in which each scale degree is denoted by a syllable.
The concept of harmonic function originates in theories about just intonation.It was realized that three perfect major triads, distant from each other by a perfect fifth, produced the seven degrees of the major scale in one of the possible forms of just intonation: for instance, the triads F–A–C, C–E–G and G–B–D (subdominant, tonic, and dominant respectively) produce the seven ...
Moving to the subdominant is a standard practice in the trio section of a march in a major key, while a minor march will typically move to the relative major. Changes of key may also represent changes in mood. In many genres of music, moving from a lower key to a higher often indicates an increase in energy.
In music, the tonic is the first scale degree of the diatonic scale (the first note of a scale) and the tonal center or final resolution tone [1] that is commonly used in the final cadence in tonal (musical key-based) classical music, popular music, and traditional music. In the movable do solfège system, the tonic note is sung as do.
