494. HOW TO UNLOCK THE IMPROVISATION OF BASS-LINES WITH THE ISOKRATIC TRINITY OF TONAL, SUBDOMINANT AND DOMINANT NOTES 1-4-5.

493. THE DIMINISHED 7NTH CHORD IS A GATE TO RESOLVE TO 4 DIFFERENT TONALITIES

 

THE DIMINISHED 7NTH CHORD IS A GATE TO RESOLVE TO 4 DIFFERENT TONALITIES

7dim7 = 7 2 4 5#

By lower by a semitone one note of the diminished 7th chord, we result to a major dominant 7th chord, which in its turn resolves to a major chord, which has root i again another note of the initial diminished 7th chord but one semitone higher

7dim7 =7 2 4 5#  via  5M7=7 2 4 5 resolve to  1M

7dim7 =7 2 4 5#  via  3M7= 7 2 3 5 #resolve to  6M

7dim7 =7 2 4 5#  via  1#M7= 7 1# ,4, 5#  resolve to  4#M=5bM

7dim7 =7 2 4 5#  via  7bM7=7b 2 4 5 # resolve to  2#M=3bM

E.g.

THE DIMINISHED 7NTH CHORD IS A GATE TO RESOLVE TO 4 DIFFERENT TONALITIES

Bdim7 = b d f g#

By lower by a semitone one note of the diminished 7th chord, we result to a major dominant 7th chord, which in its turn resolves to a major chord, which has root i again another note of the initial diminished 7th chord but one semitone higher

Bdim7 =b d f g#  via  GM7=b d f g resolve to  CM

Bdim7 =b d f g#  via  EM7= b d e g# resolve to  AM

Bdim7 =b d f g#  via  C#M7= b c# ,f, g#  resolve to  F#M=GbM

Bdim7 =b d f g#  via  BbM7=Bb d f g # resolve to  D#M=EbM

492. THE CHORD TRIAD (7M7, 3m, 4M) , OR (3M7,6m, 7bM).

 

The    4M->7M7->3m   or  the

7bM->3M7->6m 

is sometimes called The Neapolitan Progression or cadenza

489. MELODY IMPROVISATIONS WITH 3 LAYERS OF HARMONIC, MELODIC AND CHROMATIC STRUCTURE

The main idea is to include the harmony in the structure of the melodu improvisation.

And in order to do so, we create melodies that 

1) Have harmonic moves (corresponds to harmonic cycles of chords)

2) Melodic waves (corresponds to chord arpeggios)

3) Chromatic ripples (corresponds to chromatic embellishments or chromatic arpeggios) 

Examples of melodies with quite clear such structure are

1) The improvisational melodies of overtone flutes

2) The Dan Bau (or duxianqin ) improvisation melodies

3) The trombone improvisation melodies

4) Mongolian Morin Khuur cello, improvisation melodies

5) Chinese vilin Erhu, improvisation melodies

488. Drone playing per tetra-chord and per- scale in Irish Bouzouki and overtone tunings. Ancient methods of voice improvisation accompanied with intervals of 5ths or 8ths.

The drone playing is similar to the finger-picking in guitar playing. In finger-picking we try to play simultaneously, the melody and the underlying chords. In drone-playing the underlying chord is only one, note,  the 1st or 5th of the underlying chord, or both.  And these 1 or 5 are essentially open strings up or down to the string that we play the part in the current tetra-chord) of the melody. 

Inverted ukulele tunings allow also for drone playing (Inverted tuning of  G2C3E3A4 is the A2E3C4G4 , two 5ths and a 6th instead of two 4ths and a 3rd, which is more nice voicing of a minor 7nth chord)

The maximum abilities of drone playing seems to exist in the tunings like DADA or CGCG etc. but also such tunings inorder to give maximum abilities of drone playing (when  playing a melody in a  strings the other 3 strings can serve as harmonic drones, accompanying) they exclude the accompanying with ordinary major or monor 3-notes chords!!!. This forces a playing which is mostly melody (>70%) and little occupied with parallel harmonizing or chord-improvisation. Leonardo da Vinci used to sing and improvise, accompanying his voice with a continuous interval of 5th with a violin or rtaher his lira de Brachio, which later was developed into a Lireno !

The drone-playing is the model of the ancient times' voice improvisation, accompanied only with intervals of 5th ot 8ths!!! (see e.g. https://www.youtube.com/watch?v=QUcTsFe1PVs&t=24s)
