Pardon my ignorance, but what does it mean when there are two flats (bb) in front of a note? It's all over the place in Rufus Reid's book (usually on diminished chords) so I want to make sure I am playing the right notes. It's not in the legend. Does that mean the flat of a flat - a whole step down? I don't think so, since for example in a Cdim7, he marks a B with this double flat, however I believe in Cdim7 it's a Bb, straight up (a dim 7 is a flat 5,3, and 7, right??). So could someone explain this notation to me? I thought I was seeing double...
Is he telling me to play with poor intonation? ;-)
thanks,
Lawrence

A double flat is an oboe and a bassoon playing in unison. |

bb = two 1/2 steps lower = one whole step lower.
Bbb sounds like A

What you're describing C, Eb, Gb, Bb is called a half diminished by some. I've also heard it called Cm7 b5.

Is that right? | Right. half diminished 7th chords are also known as min7b5, but fully diminished 7th chords are just a stack of minor 3rds. i.e. - C, Eb, Gb, Bbb (A), ....or C#, E, G, Bb. Because they're symmetrical, there are only really three different fully diminished 7th chords...everything else is an inversion of one of the three. |
