A major tetrachord contains four notes separated by this pattern: whole step, whole step, half step. That’s the progression of any major chord, which is solid, bright, and pleasant to hear.
What are the intervals in a tetrachord?
tetrachord, musical scale of four notes, bounded by the interval of a perfect fourth (an interval the size of two and one-half steps, e.g., c–f).
What is the correct order of intervals needed to spell a major tetrachord?
The Major tetrachord uses the interval pattern tone – tone – semitone (e.g. C – D – E – F).
How do you write interval pattern of the major scale?
The sequence of intervals between the notes of a major scale is: whole, whole, half, whole, whole, whole, half. where “whole” stands for a whole tone (a red u-shaped curve in the figure), and “half” stands for a semitone (a red angled line in the figure).
What kind of intervals are used in a major scale?
When measured up from the tonic, major scales use only major intervals (2nd, 3rd, 6th, and 7th) and perfect intervals (unison, 4th, 5th, and octave). Also, the names of the intervals in the major scale correspond to the scale degree numbers.
What is the formula for a tetrachord?
The intervallic formula of the tetrachord of the major scale is “whole-step, whole-step, half-step”, which can be represented as “W, W, H” or “Why Won’t He”. So, starting from any note on the keyboard, and using the formula (W, W, H), the tetrachord can be formed.
How is major tetrachord formed?
A major tetrachord is built of a whole step, followed by another whole step, followed by a half step. Two major tetrachords placed in succession forms a major scale. For example, in C major, Tetrachord I is built with the notes C, D, E, and F.
What is the pattern for a major scale ascending?
The major scale is a collection of notes spanning an octave that follows the stepwise ascending interval pattern: Tone, Tone, semitone, Tone, Tone, Tone, semitone (T-T-s-T-T-T-s).
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 of C major?
The C major scale is in fact two tetrachords, one after the other, separated by a tone, in which case the two tetrachords are said to be combined by disjunction. The interval between F, the last note of the first tetrachord, and G, the first note of the second tetrachord, is a tone.
What is the major scale pattern?
A major scale contains a specific succession of whole and half steps. It is helpful to think of the pattern as consisting of two tetrachords. (A tetrachord is a four-note scale segment.) The lower tetrachord consists of the pattern whole step, whole step, half step.
What are the intervals of a major chord?
A major triad can also be described by its intervals: the interval between the bottom and middle notes is a major third and the interval between the middle and top notes is a minor third. By contrast, a minor triad has a minor third interval on the bottom and major third interval on top.
What is the interval pattern of a minor scale?
Minor Scales
The scale that is created by playing all the notes in a minor key signature is a natural minor scale. To create a natural minor scale, start on the tonic note and go up the scale using the interval pattern: whole step, half step, whole step, whole step, half step, whole step, whole step.
What is the specific interval pattern of C major?
C Major Scale
If we are to play each note available to us on any Western instrument in an ascending or descending order, then each note will be one half step away from the next. Thus, when ascending from C in half steps, we get C, C#, D, D#, E, F, F#, G, G#, A, A#, B, and back to C.
What are the intervals in C major?
1. C major scale
| Note no. | Note interval | Note name |
|---|---|---|
| 1 | tonic | The 1st note of the C major scale is C |
| 2 | C-maj-2nd | The 2nd note of the C major scale is D |
| 3 | C-maj-3rd | The 3rd note of the C major scale is E |
| 4 | C-perf-4th | The 4th note of the C major scale is F |
