Here’s a little something for the weekend.
Blues scales are a good way to start improvising. Based on the Major scale, the Blues Scale is made up of:
Root
Flattened 3rd
4th
Flattened 5th
5th
Flattened 7th
Octave
So following this formula, you can work out all the blues scales if you know the Major scales.
The attached sheet gives you the Blues scales up to 5 flats and 6 sharps, so there are still 3 to work out for yourselves.
Don’t try to enharmonically transpose them, because composers don’t!
At the end of each scale on the sheet is a phrase for you to learn. However, that phrase is only in 1 key. As you can see, I have numbered the first phrase so that you can easily try that phrase in different keys by using the same numbers.
Ideally, you should play the scale over the whole range if the instrument and also play the modes too. This will give you more ammunition for improvising.
Let me know how you get on.
Have a good weekend
