Saxophone beginners Transposing Bb to G harmonic minor?

[wakyct]

Hey all, I have a basic question but web searching isn't providing much clarity.

I'm transposing concert Bb harmonic minor to my alto, so G harmonic minor. If it was a major key it's straightforward, but with the b3 and b6 of harmonic minor, how should I write the key signature (since G has one sharp, F)?

Can I mix sharps and flats in the signature? Or should I use accidentals for the flats?

The key sig for G minor is two flats, Bb and Eb - same as the relative major. You ignore the fact that a harmonic minor scale has a major 7. That can be added where necessary as an accidental.

Try this:
Playing along on Alto Sax, with Adagio in G minor, concert key, one of my favorites.
Great theme for Latin/Salsa improv.
