A 2nd version of the 1st overtones tuning (see post 191) is starting from the 2nd overtone till the 8th omitting the 7nth overtone thus
C2-G2-C3-E3-G3-C4 INTERVALS (5-4-3M-3m-4) or in semitones (7-5-4-3-5 ) in numbered steps of the diatonic scale 1-5-1'-3'-5'-1"
AND IF WE WANT TO HAVE THE INTERVAL OF 5TH AT THE TWO HIGHEST STRINGS AS IT SOUNDS BETTER WITH CLARITY (AS IS THE CAE ALSO WITH THE CHARANGO TUNING) WE SET THE CUATRO CAVACO FIRST LOWER AND THEN HIGHER THE TROLL TUNING INVERTED THUS
G2-C3-E3-G3-C4-G4 INTERVALS (4-3M-3m-4-5) or in semitones (5-4-3-5-7 ) in numbered steps of the diatonic scale 5-1'-3'-5'-1"-5" and as overtone orders it is 3-4-5-6-8-12 overtones.
We may call it 5th version of the overtones tuning.
Furthermore a slight variation of thsiversion of overtones tuning so as to include the stanrd ukulele-guitar tuning (or venezuela cuatro) and thsu be more familiaer in at least 4 strings is the
C2-G2-C3-E3-A3-C4 INTERVALS (5-4-3M-4-3m) or in semitones (7-5-4-5-3 ) in numbered steps of the diatonic scale 1-5-1'-3'-6'-1" It is an open tuning of th root major with 6th as the open tuning of ukulele.
Still another variation of the overtones tuning which includes not only the ukulele (venezuela cuatro) but also the charango tuning besides of course the troll tuning and the 3-string Bouzouki tuning is the C2-G2-C3-E3-A3-E4 INTERVALS (5-4-3M-4-5) or in semitones (7-5-4-5-7 ) which is symmetric as we see and in numbered steps of the diatonic scale 1-5-1'-3'-6'-3" It is an open tuning of the root major with 6th as the open tuning of ukulele and charango.
We may compare these tuning with that of the fado guitar that in interavls it is (5-2-5-4-2) E.g. C-G-A -E-A-B) it is an open major chord with 6th and major 7nth
AND IF WE WANT TO HAVE THE INTERVAL OF 5TH AT THE TWO HIGHEST STRINGS AS IT SOUNDS BETTER WITH CLARITY (AS IS THE CAE ALSO WITH THE CHARANGO TUNING) WE SET THE CUATRO CAVACO FIRST LOWER AND THEN HIGHER THE TROLL TUNING INVERTED THUS
G2-C3-E3-G3-C4-G4 INTERVALS (4-3M-3m-4-5) or in semitones (5-4-3-5-7 ) in numbered steps of the diatonic scale 5-1'-3'-5'-1"-5" and as overtone orders it is 3-4-5-6-8-12 overtones.

The current 2nd overtone tuning tuning unlike the 1st overtones tuning in post 191 WHICH is FROM THE 1ST OVERTONE TO THE 6TH, here it is FROM THE 2ND OVERTONE TO THE 7NTH
(it is an open tuning and an major chord with major 7nth)
In intervals of 5th 4th 3rd itis 5-4-3M-3m-3M
E.G.FROM C2 as C major scale IT IS C2-G2-C3-E3-G3-B3
FOR D MAJOR IT IS
D2-A2-D3-F#3-A3-C#4
FOR F MAJOR IT IS
F2-C3-F3-A3-C4-E4
For such an F major tuning and for optimal tensions the 4th D3 string of the standard guitar must be changed to a 3rd G3 string, and the 6th E2 string of the stnard guitar must be changed to a 6th A2 string.
FOR G-MAJOR IT IS
G2-D3-G3-B3-D4-F#4
FOR Bb major it is
Bb2 F3 Bb3 D4 F4 A4
FOR Eb IT IS
Eb2-Bb2-Eb3-G3-Bb3-D4
1)The part 5-4-3M IS THE SWEDISH TROLL TUNING of the violin
2) The part 4-3M is the tuning of 3 of the string of the guitar , and of ukulele, and of the Greel 4-strings bouzouki.
3) The part 4-3M-3m is the Brazilian cuatro (cavaco) tuning
4)And the part 3M-3m-3M is the melodic-harmonic tuning as in post 90 which has the maximal number of major-minor chord triads on the fret board.
5) The part 5-4 is also a Greek 3-string bouzouki and it has the maximum number of 1 or 3 frets power chords among all other tunings.
6) The part 3M-3m is also the tuning if the instrument panduri.
The logic of this tuning is similar to the logic that a trumpet is played.
The 6 strings correspond to the overtones from 2 to 7 of the blowing stength of the trumpet player. The frets of the guitar correspond to the valves and keys of the trumpet.
For all these reasons as it contains tunings of 6 different instruments , it makes miracles as improvisation tuning for the Guitar.
SOMEHOW PLAYING IN SUCH A GUITAR IS LIKE LEARNING SIMULTENEOUSLY 5 DIFFERENT INSTRUMENTS 1) A GREEL 3-STRING BOUZOUKI, 2) A SWEDISH TROLL TUNING VIOLIN , 3) A BRAZILIAN CUATRO, 4) A RUSSIAN PANDURI, 5) A MELODIC-HARMONIC CUATRO.
One of the great advantages compared to the standard guitar tuning his is that
1) The part of the tuning 4-3M-3m-4M allows for standard cuatro playing or ukulele palying of chords. The part 4-3M for standard guitar or ukulele chords. Thus when soloing on the highest 1st string, we may accompany by the opena= major root chord at 2nd 3rd and 5th string.
2) The Swedisg troll part of the tuning 5-4-3M allows for accomanying with a power root chord 5-4 (whichs is also the tuning of the Greek and Irish 3-string Bouzouki) at strings 6th, 5th, 4th , complicated soloing on the 2nd and 3rd (from higher) string that normally would require many major or minor chords for accomanying.
Thus this tuning combines techniques of the ancient 1st generation music with the techniques of the 2nd generation classical period of music.
It is a great way to link the guitar to the unity of one musical note and its overtones,and at the same time have it as open-chord tuning (it is a an major chord with major 7nth)
OTHER ADVANTAGES OF THE 1ST OR 2ND OVERTONES TUNING COMPARED TO THE STANRD GUITAR ARE
3) The shapes of the 3 inversions of the major , minor chords and dominat 7nth are in total utilzing less consecutive frets each chords thus it is has higher dnesity of chord-triads and thus it is played easier than the standard guitar
4) It is open tuning thus it allows for nice open strings root-chord (either as power-chord or as major chord) accompanying of soling on a string and inside the scale.
5) The shapes of the patterns of the chords especially for the 1st overtone tuning
5-4-3M-3m-4 are rather symmetric around the 3rd string (for the higher 5 strings) therefore easier to comprehend and play in improviations where it is orefered to play 3-consecutive strings or 4-consecutive string chords only.
6) Because it includes the above 4-5 instruments of 3 or 4 string it is easy to play when you know the simpler instruments. Conversely playing this guitar makes you learn all the above instruments.
7) As it is an open major chord shape , the corresponding one fret major chord pattern sounds better as voicing comprated to the corresponding 3 inversions of major chords in the standard guitar , because it is the sequence of harmonics from 2 to 8 (excluding the 7nth).
8) Especially the 2nd overtones tuning (all overtones from 2nd to 7nth , 5-4-3M-3m-3M) in its major or minor chord triads has more normal forms compared to the normal forms of the standrad tuning, thus it sounds better.
9) Because the chords are in one or 2 only frets, their arpeggios also and neighboring melodies are in fewer frets thus easier to play as finger picking style.
A variation of this 2nd overtone so as to include the ukulele tuning rather than the cuatro cavaco tuning is (for C major ) the C2-G2-C3-E3-A3-C4 (5-4-3M-4-3m). Notice that it still includes the troll tuning . It is open chord 6m7 tuning.
Or C2-G2-C3-E3-A3-E4 (5-4-3M-4-5) which is combination of the Swedish troll tuning and charango tuning. Still open 6m7 chord or 1M6
Or C2-G2-C3-E3-G3-C3 5-4-3M-3m-4 (Open 1Major chord) which is a version of the 1st overtones tuning (see post 191 ) which start from the 2nd ove tone and ends to the 8th overtone omittingthe 7nth overtone .
