The first note of the tetrachord is also the first note of the scale. The second note of the tetrachord (in descending order) is the first of the scale. The third note of the tetrachord (in descending order) is the first of the scale.
What are the types of tetrachord?
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.
What are the four tetrachords?
In Western music, the tetrachord is an ascending series of four notes. Two disjunct tetrachords (those without a common tone), each with the interval arrangement of tone, tone, semitone, combine to form the major scale. Thus the tetrachords c–d–e–f and g–a–b–c′ form the scale built on c.
What is a tetrachord in music?
A tetrachord is just four notes. The majority of Western scales have 8 notes, so a tetrachord can be thought of as half of a scale. Just as an interval is a basic building block in music, a tetrachord is a (larger) building block of a scale. Two tetrachords combine to form a scale.
What is the 2nd tetrachord in the key of a major?
The two Tetrachords in the Major Scale are separated by a Whole Step. In the C Major Scale, the first tetrachord is made up of the notes C – D – E – F. The second tetrachord is made up of the notes G – A – B – C. Each Tetrachord has the same interval structure: Whole Step, Whole Step, Half Step.
What is the second tetrachord?
The second tetrachord is the minor tetrachord – the half step is between the second and third notes (so the step pattern is whole-half-whole). This is also the first four notes of the minor scale.
What is the second tetrachord called?
The second note of the tetrachord (in descending order) is the first of the scale. The third note of the tetrachord (in descending order) is the first of the scale.
What is the first tetrachord of the G major scale?
The 2nd tetrachord of the C major scale is the 1st tetrachord of the G major scale.
What is an example of a tetrachord?
In a diatonic tetrachord, the three intervals used are two whole tones and one semitone. An example would be a Major or minor tetrachord (e.g. C – D – E – F or A – B – C – D).
How do you make a tetrachord?
The upper minor (or Phrygian) tetrachord is built with a half step, followed by a whole step, followed by a whole step. In C natural minor, Tetrachord II is built with the notes G, A♭, B♭ , and C. As G to A♭ is a half step, A♭to B♭ is a whole step and B♭ to C is a whole step.
What is a Phrygian tetrachord?
Quick Reference. A tetrachord made up of the first four notes of the Phrygian mode. The intervals of the Phrygian tetrachord are semitone–tone–tone (e.g. E–F–G–A), as opposed to the tone–tone–semitone of the diatonic major scale.
What is the tetrachord for D?
The lower tetrachord of a D major scale is made up of the notes D, E, F#, and G. The upper tetrachord is made up of the notes A, B, C#, and D. These two 4-note segments are joined by a whole-step in the middle.
What is a Trichord in music?
In music theory, a trichord (/traɪkɔːrd/) is a group of three different pitch classes found within a larger group. A trichord is a contiguous three-note set from a musical scale or a twelve-tone row.
