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.
