What is a quartal voicing?
The term “quartal” in music refers to the interval of a fourth. When musicians refer to quartal voicings they are referring to chords that are built using intervals of a fourth (as opposed to intervals of a third, like major or minor triads, which are referred to as “tertian”).
What is a quartal melody?
In music, quartal harmony is the building of harmonic structures built from the intervals of the perfect fourth, the augmented fourth and the diminished fourth. For instance, a three-note quartal chord on C can be built by stacking perfect fourths, C–F–B♭.
What is a Tertian Triad?
Written by Arthur in Music Theory. Tertian harmony describes music and chords constructed with thirds. Based on the diatonic scale, and the basic concept of intervals, these thirds are either minor (an interval of 3 semitones) or major (an interval of 4 semitones).
What is a Polychord in music?
🔗 A polychord typically consists of two triads sounding simultaneously. A polychord could also consist of two seventh chords, or a seventh chord and triad. Additionally, a polychord could conceivably consist of more than two triads or seventh chords, since the prefix “poly” means “many.” 🔗
How do you construct quartal harmony?
For example, playing C and F together produces a sound that characterizes quartal harmony. If you stack another fourth (Bb) on top of the C and F, you get a typical quartal harmony voicing. Add more on top or below and you get really open-sounding chords.
What are Tertian sonorities?
A tertian chord is any harmonic sonority whose voicing emphasizes major and minor thirds. You should know triads and 7th/9th/11th/13th chords (see earlier chapters). Here are more tertian chords: Split-third chord: Triad or 7th chord with major AND minor 3rds. Above: F minor + F major (voicing varies).
What is a Tertian leap?
Tertian Leap (root movement 4th & 5th apart) best used when changing between closed and open chords. keep one common tone, voice that has the 3rd in the first chords becomes the 3rd in the second chord, other voice moves by step. ( Tonal Harmony, pg 84)
How many Tetrachords are there?
There are four main arrangements of tetrachords: the major tetrachord, the Dorian tetrachord, the Phrygian tetrachord, and the Gypsy tetrachord. Each one features a different pattern of intervals between the four notes of the chord and produces a different sound.
How do you make polychord?
The best way to start experimenting with polychords is to use the circle of fifths. Choose a base chord that’ll live in the lower voice, and use the rest of the circle of fifths for the upper voices. The further away you get from the home key, the darker sounding it will get.
What is the octatonic scale in jazz?
The octatonic or diminished scale is an eight note scale in which the intervals alternate between whole and half steps. This scale is sometimes used in jazz. Similarly to the whole tone scale, octatonic scales don’t imply a particular central pitch.
How do you identify an octatonic scale?
The octatonic is a mode of (very) limited transposition, and there are three possible scales: Oct 0,2; Oct 0,1; and Oct 1,2. The numbers of the names indicate all that is needed to identify a particular octatonic scale: two consecutive notes within the scale. 0 is C♮, 1 is C#, and 2 is D♮.
