…and the upper tetrachord of the A melodic minor scale: while the upper tetrachord consists of E, F#, G# and A:ĭue to the fact that the upper tetrachord of the A natural major scale:
The lower tetrachord consists of A, B, C#, and D: Let’s take a look at the lower and upper tetrachords of the A natural major scale: “A Contrast Between The Upper Tetrachords Of The Natural Major And Melodic Minor Scales…” …can be broken down into its lower tetrachord: …a set of four notes, while the upper tetrachord consists of E, F#, G#, and A: …the lower tetrachord consists of A, B, C, and D: On the piano, the first four notes of a scale is the lower tetrachord while the last four notes belong to the upper tetrachord. Violin players are familiar with the tetrachord because they play all the notes of the major scale using only two strings – four notes per string.Įvery traditional scale can be broken down into two tetrachords (four notes per string), the lower and upper tetrachords. Tetra means four while chord means notes. Tetrachord comes from two Greek words – tetra and chord. To take you to the next level in this lesson, let’s divide the melodic minor scale into two equal parts (aka – “tetrachord”.) The Upper And Lower Tetrachords Of The Melodic Minor Scale “For Your Reference, Here’s The Melodic Minor Scale In All Twelve Keys…” …are raised by a half step (to F# and G#): That its sixth and seventh degrees (F and G): The melodic minor scale can be considered as a natural minor scale with its sixth and seventh degrees raised by a half step. …named after the melodic problem it solved, hence, the name melodic minor scale. …to form another chromatic variant (of the natural minor scale): In a bid to solve the melodic problem of the harmonic minor scale, the sixth degree of the harmonic minor scale (which is F): (If you are from a classical background, you’ll probably remember that all augmented and diminished intervals are dissonant.) The augmented second interval between the sixth and seventh tones of the harmonic minor scale sounded harsh, and constituted a melodic problem. The interval from the sixth degree of the A harmonic minor scale (which is F): …is a gapped scale that has a dissonant melodic interval between its sixth and seventh tones (F and G#): Raising the seventh tone of the A natural minor scale: The melodic minor scale was derived from the harmonic minor scale (another chromatic variant of the natural minor scale) which is formed by raising the seventh degree of the natural minor scale by a half step “Before We Proceed, Why Is It Called The Melodic Minor Scale?” In a nutshell, the melodic minor scale is a natural minor scale modified with chromatic or foreign notes. …which are foreign to the key of A minor. …contains a modification of the sixth and seventh tones from F and G:
…is the traditional scale of the key of A minor, hence, it outlines all the notes in the key of A minor. The term chromatic is used to describe an idea (be it a note, scale, interval, chord, or chord progression) that is foreign to a given key. Simply put, the melodic minor scale is a chromatic variant of the natural minor scale. The natural minor scale has two chromatic variants – the harmonic minor and the melodic minor scales. The traditional scale of the major key is the natural major scale, while that of the minor key is the natural minor scale. The traditional scale of a key gives you an outline of the notes in that key. A Note On The Melodic Minor ScaleĮvery key (whether major or minor) has its traditional scale. I’ll be explaining why the ascending form of the melodic minor scale differs from its descending form, but before we do that, let’s do a review on the melodic minor scale. The only difference between both may just be the order of the notes. Most scales on the piano have an ascending form that is related to the descending form. If you want to know why the ascending form of the melodic minor scale differs from its descending form, then this lesson is for you!.
