An eighth note or a quaver is a musical note played for one eighth the duration of a whole note (semibreve). Its length relative to other rhythmic values is as expected—e.g., half the duration of a quarter note (crotchet), one quarter the duration of a half note (minim), and twice the value of a sixteenth note.
As the name implies, a quarter note's duration is one quarter that of a whole note, half the length of a half note, and twice that of an eighth note. It represents one beat in a bar of 4 4 time. The term "quarter note" is a calque (loan-translation) of the German term Viertelnote.
A semitone is thus made of two steps, and three steps make a three-quarter tone or neutral second, half of a minor third. The 8-TET scale is composed of three-quarter tones. Four steps make a whole tone. Quarter tones and intervals close to them also occur in a number of other equally tempered tuning systems.
The size of an interval between two notes may be measured by the ratio of their frequencies.When a musical instrument is tuned using a just intonation tuning system, the size of the main intervals can be expressed by small-integer ratios, such as 1:1 (), 2:1 (), 5:3 (major sixth), 3:2 (perfect fifth), 4:3 (perfect fourth), 5:4 (major third), 6:5 (minor third).
The abbreviations col 8, coll' 8, and c. 8 va stand for coll'ottava, meaning "with the octave", i.e. to play the notes in the passage together with the notes in the notated octaves. Any of these directions can be cancelled with the word loco , but often a dashed line or bracket indicates the extent of the music affected.
In the theory and practice of music, a fifth interval is an ordered pair of notes that are separated by an interval of 6–8 semitones. There are three types of fifth intervals, namely perfect fifths (7 semitones), diminished fifth (6 semitones), and; augmented fifth (8 semitones).
A rest may also have a dot after it, increasing its duration by half, but this is less commonly used than with notes, except occasionally in modern music notated in compound meters such as 6 8 or 12 8. In these meters the long-standing convention has been to indicate one beat of rest as a quarter rest followed by an eighth rest (equivalent to ...
