There are two half-steps in the key of F: A to B flat and E to F
There are two half-steps in the key of D: F# to G and C# to D
Take a look at any keyboard. Each key is one half step away from the next. So if you were on an F#, a black key, and you moved up to the next white key, a G, you have gone one half step.
There are two half-steps in the key of A: C# to D and G# to A
It is two half-steps lower than a B, resulting in an A.
The half-steps are between the 2nd and 3rd scale degrees, and between the 5th and 6th scale degrees. In the key of A minor, that's between B and C, and E and F.
In order to help you with this, I need to explain the concept of "whole steps" and "half steps." (If you already know this, then skip the following paragraph.) Half steps (H) are between a white key and a black key on a piano (or white key to white key if there's no black key in-between). Whole steps (W) are two half steps (and not always white key to white key). The pattern would be this: W W H W W W H Here's an example: C: C D E F G A B C W W H W W W H There's a whole step between C and D, D and E, F and G, etc as well as a half step between E and F, and B and C. In other words, there are only a half step between the 3rd and 4th note in an octave, and the 7th and 8th. Lets say you want the key of G: G A B C D E F# G We have to sharpen the F (ie., use a black key) to go up a whole step from the E and to have a half step back to the G.
2 sharps is D Major or b minor. The two sharps in this key are F# and C#, so you just have to look at the second sharp (C#) and move up a half step for the key (D). To find its minor equivalent, move down three half steps (3 half steps below D is B natural).
To change the key of a song using an F capo on a guitar, place the capo on the second fret of the guitar neck. This will raise the pitch of all the strings by one and a half steps, effectively changing the key of the song to F.
In a natural minor scale, the half steps occur between the 2nd and 3rd degrees and between the 5th and 6th degrees of the scale. For example, in the key of A natural minor, the half steps occur between B and C, and between E and F.
A half step is a half step. It is also called a minor third. There is no "major" when it comes to half steps. If you meant the half steps on white keys on a keyboard, then that would be B-C and E-F.
there are 90 i believe
