This could be glaringly obvious but i can't work it out.. if you go to the scales page, select pentatonic minor in A you get this in the description: 1,b3,4,5,b7 I assumed 1=A, so therefore 2=A# 3=B etc but that doesn't seem to be the case... can anyone explain? cheers!

 Wiard 4 Jul 2006 05:54 | Quote Posts: 3 Hi! The numbering is derived from the (regular) Major scale. A Major goes: 1=a, 2=b, 3=cis. In a Minor scale the third gets flat (3=c). That's where the b stands for - a flat third.
