Play Cmaj9 chord (see chord symbols) Play In music, a ninth is a compound interval consisting of an octave plus a second. Like the second, the interval of a ninth is classified as a dissonance in common practice tonality. Since a ninth is an octave larger than a second, its sonority level is considered less dense.[1] Contents [hide] 1 Major ninth 1.1 Transposition 2 Minor ninth 3 Augmented ninth 4 Ninth chords 5 See also 6 Sources Major ninth[edit] A major ninth is a compound musical interval spanning 14 semitones, or an octave plus 2 semitones. If transposed into a single octave, it becomes a major second or minor seventh. The major ninth is somewhat dissonant in sound. Transposition[edit] Some common transposing instruments sound a major ninth lower than written. These include the tenor saxophone, the bass clarinet, the baritone/euphonium when written in treble clef, and the trombone when written in treble clef (British brass band music). When baritone/euphonium or trombone parts are written in bass clef or tenor clef they sound as written. Minor ninth[edit] A minor ninth (m9 or -9) is a compound musical interval spanning 13 semitones, or 1 semitone above an octave (thus it is enharmonically equivalent to an augmented octave). If transposed into a single octave, it becomes a minor second or major seventh. The minor ninth is rather dissonant in sound, and in European classical music, often appears as a suspension. Béla Bartók wrote a study in minor 9ths for piano. The fourth movement (an intermezzo) of Robert Schumanns Faschingsschwank aus Wien, is a constructed to feature prominent notes of the melody a minor ninth above the accompaniment. Alexander Scriabins Piano Sonata No. 9, Black Mass is based around the interval of a minor ninth, creating an uncomfortable and harsh sound. Augmented ninth[edit] Augmented ninth on C. Play An augmented ninth is a compound musical interval spanning 15 semitones, or 3 semitones above an octave. Enharmonically equivalent to a compound minor third, if transposed into a single octave, it becomes a minor third or major sixth. It is a consonant interval. See: Dominant seventh sharp ninth chord. Ninth chords[edit] Main article: Ninth chord Dominant ninth chord on C. Play Major ninth chord on C. Play Minor ninth chord on C. Play Three types of ninth chords may be distinguished: dominant (9), major (M9), and minor (m9).[2][3] They may easily be remembered as the chord quality of the seventh does not change with the addition of the second scale degree,[2] which is a major second in both major and minor, thus: 0 4 7 t + 2 = dominant seventh + ninth = dominant ninth chord 0 4 7 e + 2 = major seventh + ninth = major ninth chord 0 3 7 t + 2 = minor seventh + ninth = minor ninth chord The dominant ninth (V9) is a dominant seventh plus a major or minor ninth.[4] See also[edit] Augmented octave Augmented unison Sources[edit] Jump up ^ Westergaard, Peter (1975).

In minor keys a similar chromatic change from minor to major takes places. [show] v t e Chord factors [show] v t e Intervals (list) Categories: Chord factorsSeconds (music) ~W
