Perfect fourth

In classical music from Western culture, a fourth spans exactly four letter names (staff positions), while a perfect fourth (harmonic series) always involves the same interval, regardless of key (sharps and flats) between letters. A perfect fourth is the relationship between the third and fourth harmonics, sounding neither major nor minor, but consonant with an unstable quality (additive synthesis). In the key of C, the notes C and F constitute a perfect fourth relationship, as they're separated by four semitones (C, C#, D, D#, E, F). Up until the late 19th century, the perfect fourth was often called by its Greek name, diatessaron. A perfect fourth in just intonation corresponds to a pitch ratio of 4:3, or about 498 cents, while in equal temperament a perfect fourth is equal to five semitones, or 500 cents. The perfect fourth is a perfect interval like the unison, octave, and perfect fifth, and it is a sensory consonance. In common practice harmony, however, it is considered a stylistic dissonance in certain contexts, namely in two-voice textures and whenever it appears above the bass. If the bass note also happens to be the chord's root, the interval's upper note almost always temporarily displaces the third of any chord, and, in the terminology used in popular music, is then called a suspended fourth. Conventionally, adjacent strings of the double bass and of the bass guitar are a perfect fourth apart when unstopped, as are all pairs but one of adjacent guitar strings under standard guitar tuning. Sets of tom-tom drums are also commonly tuned in perfect fourths. The 4:3 just perfect fourth arises in the C major scale between G and C.

Secondary chord

A secondary chord is an analytical label for a specific harmonic device that is prevalent in the tonal idiom of Western music beginning in the common practice period, the use of diatonic functions for tonicization. In the tonal idiom, a song or piece of music has a tonic note and chord, which is based on the root of the key that the piece is in. The most important chords in a tonal song or piece are the tonic chord (labeled as I in harmonic analysis) and the dominant chord (V). A piece or song is said to be in the key of the tonic. In the key of C major, the tonic chord is C major and the dominant chord is G. Chords are named after the function they serve and their position (for example, the "dominant" is considered the most important after the tonic and the "subdominant" is the same distance from the tonic as the dominant but below rather than above) and numbered by the scale step of the chord's base note (the root of the vi chord is the sixth scale step). Secondary chords are altered or borrowed chords, chords which are not in the key. Secondary chords are referred to as the function they are serving of the key or chord to which they function and written "function/key". Thus, the dominant of the dominant is written "V/V" and read as, "five of five," or, "dominant of the dominant". Any scale degree with a major or minor chord on it may have any secondary function applied to it; secondary functions may be applied to diminished triads in some special circumstances. Secondary chords were not used until the Baroque period and are found more frequently and freely in the Classical period, even more so in the Romantic period, and, although they began to be used less frequently with the breakdown of conventional harmony in modern classical music, secondary dominants are a "cornerstone," of popular music and jazz of the 20th century.Benward & Saker (2003), p.273-7.
