What intervals are used in an octatonic scale?
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.
What is a scale with 8 notes called?
An octatonic scale is any eight-note musical scale. However, the term most often refers to the symmetric scale composed of alternating whole and half steps, as shown at right.
What are the notes in 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.
What are the 3 diminished scales?
The Diminished Scale
Because it is a symmetrical scale (and much like the diminished chord) there are only three unique diminished scales: C = E♭ = G♭ = A diminished scale. D♭ = E = G = B♭ diminished scale. D = F = A♭ = B diminished scale.
How do you use octatonic scale?
A fully diminished seventh chord is every third note of the scale. And if you play the notes that are in between if I can squeeze my fingers in there it's another fully diminished seventh chord. So.
How do you label an octatonic scale?
There are three octatonic scales, and they’re typically labeled by what’s going on around C. You either have a half step from C to C#, yielding the label OCT[0,1], a half step from C# to D for OCT[1,2], or a whole step from C to D to make OCT[0,2] (in lieu of going to OCT[2,3]).
Why are there 8 notes in a scale?
The next pitch is called the octave because it’s the eighth note (just as an octopus has eight legs). More than a thousand years ago the letters of the Roman alphabet were adopted to refer to these, and since there were only seven the letters ran A, B, C, D, E, F, G.
What does octatonic mean in music?
Definition of octatonic
: relating to or employing an eight-note scale made up of alternating semitones and whole tones … a French sixth chord, which contains two tritones, acts as a nexus between the whole-tone scale, which contains three, and the octatonic scale, which contains four.—
What is octatonic scale guitar?
The scale is sometimes called whole-half scale, or octatonic scale. Whole-half is a useful name as it spells out the construction of intervals; start from any root note and go up a whole tone, then a semitone, then a whole tone and a semitone.
What are the intervals of a diminished scale?
In the case of the diminished scale, the repeated interval sequence is alternating half-steps and whole-steps. Thus, there are two diminished scales, depending on which interval (half-step or whole-step) you start with. We call these scales the “whole/half diminished scale” and the “half/whole diminished scale”.
What is a diminished 7th scale?
In classical music from Western culture, a diminished seventh ( play (help·info)) is an interval produced by narrowing a minor seventh by a chromatic semitone.
What’s the diminished scale?
The diminished scale is a symmetric scale formed by the sequence: Tone – Semitone – Tone – Semitone – Tone – Semitone – Tone. In the same way that we observed for the diminished chord, the diminished scale is repeated every three semitones. This is very advantageous, as it opens up a very wide range of possibilities.
Which is octatonic?
An octatonic scale consists of alternating whole and half steps. It is an eight-tone scale; that is, eight tones are required to fill in the octave.
What chords from octatonic scale?
The dominant seventh chords of E, C#, Bb and G are taken from the same octatonic scale and are a third apart, all four roots making up a diminished seventh as explained above.
How many octatonic collections are there?
three octatonic collections
There are only three octatonic collections. The interval content of this collection is very homogenous, and this intervallic consistency leads to one of its most interesting properties.
How many unique octatonic scales are there?
three unique octatonic collections
And as a result of the property, there are only three unique octatonic collections. We name these arbitrarily as OCT(0,1), OCT(1,2), and OCT(2,3). The numbers to the right of “OCT” are pitch classes within that scale.
How do you make a Phrygian scale?
To create the A Phrygian scale, for example, start with that movement of a semitone that takes you from A to Bb. Then move by four full tones through the notes C, D and E. You can then move by a semitone once again to reach the F, before jumping by another two tones: G and A. That’s it.
Can a scale have 9 notes?
The Nine Tone Scale is somewhat uncommon with its nine notes. It reminds a little of the Augmented Scale, and we can see a similarity comparing C Augmented Scale and C Nine Tone Scale, which both include Eb and G#.
What is a 9 note scale called?
Nonatonic (9 notes per octave): a chromatic variation of the heptatonic blues scale. Octatonic (8 notes per octave): used in jazz and modern classical music. Heptatonic (7 notes per octave): the most common modern Western scale.
What is a 9 note scale?
9-note scales are called nonatonic scales. This would just be called the whole/half/half scale. We have precedent for this naming from the two (octatonic) diminished scales, which are called whole/half and half/whole. This scale here is a variation of the whole tone scale, which is a hexatonic scale.
