[Harp-L] what tuning is this?

[bad_hat@xxxxx]

Years ago I attended a harmonica workshop led by Lee Oskar.  It was held 
at the Rhythm Room in Phoenix Arizona.  A lot of what the workshop was 
about was tuning.  Lee had us tune to an odd configuration.  I have 
never been able to figure out what the purpose of the tuning was.  I'm 
not even sure I have it right, well I have the harmonica and I can 
garner the tuning from that but did I get it right in the moment?  I 
suspect if it is in fact a useful tuning that the originator was more 
likely Kit Gamble not Lee Oskar.  Ok, typing in the tuning below.  I'd 
love to hear fro someone who knew what this was for.

Blow  C  F# A  D F# A D F# A D
Draw  G  A  C# E G  B C E  G B

Retuned from a D harmonica.  If I searched hard enough I could probably 
find the handout for this.  I wasn't adept at this.  I had retuned 
plenty but I kept tuning the wrong reed, it's not changing, it's not 
changing.  Maybe it's me, Lee didn't strike me as the most patient 
teacher.  Interesting day.
