Salut,
Le Diato vous interresse ? sachez que des techniques permettent de jouer dans toutes les tonalités avec un seul diatonique.
Il faut de preference éviter de parler en "positions", cela n'est compréhensible que pour et par des harmonicistes, pour se faire comprendre des autres musicos rien de mieux que le langage musical "ordinaire"
Un p'tit lien qui explique tout et plus

Comments:
You can play blues scale easily in:
1st, 2nd, 3rd, 4th, 5th, 6th and 8th harp positions.
For more advanced players:
7th and 12th harp positions and other octaves of the listed above.
For expert players:
9th, 10th and 11th harp positions...
(just look how many bends, overblows/overdraw you need)
Take this scales as excercises... you should know how the blues scale sounds,
so you can practice bends and overblows/overdraws.
