There are 12 different minor scales that are melodic. 2 of those have two
names, so you could brag and say that you have learned 14! Those
that have two names look exactly the same on the keyboard, but differently with notes.
Melodic minor scales are a little bit "special" since they are played differently ascending (going up) and descending (going down).
In F# and C# minor the fingering need to change slightly when descending, so watch out!
You can scroll down for all the scales, or use these quick links to get to the scale you need:
