Construirea gamelor muzicale

Dupa cum ati observat probabil am urmat la dreapta cercul si am construit gamele C, G, D, A, E. Gama Do major nu are nici un diez fiind formata numai din sunetele naturale. Celelalte game au cate 1,2,3,4...sau 7 diezi dupa cum este reprezentat in fig.


Gama G are F#
Gama D are F# C#
Gama A are F# C# G#
Gama E are F# C# G# D#
Gama B are F# C# G# D# A#
Gama F#are F# C# G# D# A# E#
Gama C#are F# C# G# D# A# E# B#

Urmand astfel cercul in momentul in care doriti sa formati o gama este suficient sa retineti numarul de diezi din dreptul acordului si sa memorati ca ordinea in care se ataseaza acesti diezi este F C G D A E B. Repetam acum formarea gamei Mi major (E) : ne uitam pe cerc si observam ca in dreptul notei E se afla 4 diezi; astfel in gama vom avea notele F C G D ridicate cu cate un semiton adica vor avea un diez. (priviti mai sus).

Urmand aceeasi metoda in cercul din stanga (invers acelor de ceasornic) dar de data asta
atasand bemoli (care scad valoarea notei cu un semiton) puteti afla gamele F Bb Eb Ab Db.
Bemolii se adauga in ordinea inversa de cum se ataseaza diezii adica : B E A D G C F.

Gama F are Bb
Gama Bb are Bb Eb
Gama Eb are Bb Eb Ab
Gama Ab are Bb Eb Ab Db
Gama Db are Bb Eb Ab Db Gb
Gama Gb are Bb Eb Ab Db Gb Cb
Gama Cb are Bb Eb Ab Db Gb Cb Fb
