298 THE TROLL-UKULELE 5-4-3M-4 AND TROLL-CAVACO 5-4-3M-3m TUNING OF THE 5-STRING GUITAR OR OUD

The  5-4-3M-4 tuning is  called so because the part 5-4 is a 3-string bouzouki and the part 5-4-3M is the Swedish troll violin tuning while the part 4-3m-4 is a  ukulele

THE CALICO OR BLACK MOUNTAIN TUNING IN THE NEXT VIDEO IS ALSO THE SWEDISH TROLL TUNING

E.g. G2-D3-G3-B3-E4

We may compare it with the charango tuning which is the 4-3M-4-5  e.g. for C major

G3-C4-E4-A4-E5



The troll-cavaco tuning is the 5-4-3M-3m e.g. G2-D3-G3-B3-D4. It is in all 5 strings an overtone tuning friom overtone 2 to overtone 6. (order of harmonic ofa  fundamental frequency : 2-3-4-5-6)


One of the great advantages of these tunings is that

a) The ukulele or cavaco part of the tuning allows for standard guitar playing of chords
b) The Swedisg troll part of the tuning allows for accomanying with  a power root chord 5-4 , complicated soloing on the 2nd (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.
