The beta chord may be created from a diminished seventh chord by adding a diminished octave. It may be created from a major chord by adding the sharpened root (solfege: in C, di is C ♯: C ♯, E, G, C ♮), [62] or from a diminished triad by adding the root's major 7th (called a diminished major 7th, or C# o Maj7.
These chords are all borrowed from the key of E minor. Similarly, in minor keys, chords from the parallel major may also be "borrowed". For example, in E minor, the diatonic chord built on the fourth scale degree is IVm, or A minor. However, in practice, many songs in E minor will use IV (A major), which is borrowed from the key of E major.
Diminished seventh chords may also be rooted on scale degrees other than the leading-tone, either as secondary function chords temporarily borrowed from other keys, or as appoggiatura chords: a chord rooted on the raised second scale degree (D ♯ –F ♯ –A–C in the key of C) acts as an appoggiatura to the tonic (C major) chord, and one ...
Its tonic chord is a diminished triad (B dim = B dim 5 min 3 = B D F, in the Locrian mode using the white-key diatonic scale with starting note B, corresponding to a C major scale starting on its 7th tone). This mode's diminished fifth and the Lydian mode's augmented fourth are the only modes that contain a tritone as a note in their modal scale.
A musical passage notated as flats. The same passage notated as sharps, requiring fewer canceling natural signs. Sets of notes that involve pitch relationships — scales, key signatures, or intervals, [1] for example — can also be referred to as enharmonic (e.g., the keys of C ♯ major and D ♭ major contain identical pitches and are therefore enharmonic).
The half diminished scale is a seven-note musical scale. It is more commonly known as the Locrian ♯ 2 scale [1] or the Aeolian ♭ 5 scale, names that avoid confusion with the diminished scale and the half-diminished seventh chord (minor seventh, diminished fifth). It is the sixth mode of the ascending melodic minor scale.
Diminished chord function is rarer but still exists. Half-diminished chords can function in the same way as fully diminished chords, such as in the chord progression CM 7 – C ♯ dim 7 – Dm 7, or Em 7 – E ♭ dim 7 – Dm 7, where the diminished chord serves as a chromatic passing chord preceding a chord with a diatonic
