The works use basically four types of scales:
1.Equal tempered scales (different to 12TET)
2.Augusto Novaro�s "Natural Music System". His first works about his microtonal theories were published in 1924.In 1951 he published"Sistema Natural de la M�sica"(Natural Musical System);in this book he explains his scales,based on fragments of the harmonic series:fundamental(in normal way),reciprocal(reversed)and complex (combining fundamental with reciprocal). Laura Corona, untitled piece 1990 For 12TET he prefers perfect fifths instead of perfect octaves(seventh root of 1.5)proposing also intermediate tunings;one of them was used at West Point organ(I don�t know if it is so tuned now).
He also built instruments in several temperaments,approaching just intonations,incluiding a 53TET lute for which he wrote a study.(I think he never played it,the present recording was made using a Yamaha SY77). Augusto Novaro: Estudio en 53
3.Golden scales developed by Isaac Borcegui and Guillermo Davalos
4.Historical scales based on the research by Alejandro Esbri.
