which key is the relative minor of A major?

Which major has 5 sharps in the key signature?

The minor key starts three semitones below its relative major, so

A major -> F# minor

5# = FCGDA, so key = B

To determine the relative minor of a major key, you can use a simple rule. The relative minor is always three semitones below the major key. In the case of A major, which has no sharps or flats in its key signature, the relative minor would be three semitones below A, which is F# minor. So the relative minor of A major is F# minor.

Now, let's move on to the second question. To figure out which major key has 5 sharps in the key signature, it's helpful to remember the order of the sharps in the circle of fifths, which goes like this: F ♯ - C ♯ - G ♯ - D ♯ - A ♯ - E ♯ - B ♯.

Since we need to find a major key with 5 sharps, we count the sharps until we reach the fifth one, which is A ♯. So, the major key that has 5 sharps in the key signature is A ♯ major.

However, it's important to note that the key of A ♯ major is not commonly used due to its complex key signature. Instead, it is common to use the enharmonic equivalent of B ♭ major, which has the same key signature (2 flats) but is easier to read and play.
