Which scale minor has 2 sharps?

Answer 1

There are 3 sharps in A major. How do I know? First you must understand that F C G D A E B are all the sharps. If A major has 3 sharps the last sharp would be G sharp. Then don't skip any black keys or white and just go to the right one step. So G sharp go to the right is A and that is your scale. The first note of the scale like example C is the name of the scale.

Note: The key of C major has No sharps or flats and therefore has No key signature!

P'S. I hope my advice helps.

Answer 2

Academically speaking, you raise a pitch class (or note) to a sharp while you lower a pitch class (or note) to a flat; i.e. D raised to D#, E lowered to Eb.

You are probably referring to the Melodic minor scale which sees its 6th and 7th degrees natural (not raised) on the way up and flattened (or lowered) on the way down.

In the tonal system the following scales are available:
Major 1,2,3,4,5,6,7,8
Natural minor 1, 2, b3, 4, 5, b6, b7, 8
Harmonic Minor 1, 2, b3, 4, 5, b6, #7, 8
Melodic Minor UP 1, 2, b3, 4, 5, 6, 7, 8 DOWN 8, b7, b6, 5, 4, b3, 2, 1

Another way of looking at scales is by tetra-chord.

In the Melodic Minor
The first tetra-chord of the scale is 1 ,2, b3, 4, up and down.
The second tetra-chord of the scale is 5, 6, 7, 8 and 8, b7, b6, 5 on the way down.

Answer 3

D major, B natural minor, E harmonic minor, & A melodic minor (up only)

Answer 4

B minor.
