I'm doing a G# Minor Harmonic scale, and there is this random x thing next to the note. What does it mean?

Question

Pretty much all in the question....

Answer 1

An x is a double sharp. So play a whole step higher. A double flat is two flats next to each other.

Answer 2

It's a double sharp.....play the note two half steps above.

Answer 3

double sharp.  go up 2 half steps from the original note.
