What note is scale degree 7 in a key? For example, in A Major, it seems to me it might be A but I do not know.
How do you determine which note corresponds to the 7th scale degree. What about the other notes and their corresponding degree?
First of all, a question like this can be easily answered with a simple google search. If you search for A-Major scale on line, one of the results will be: Basic Music Theory dot com A Major Scale
The following two images from that site show the entire A-Major Scale. The first shows the notes on the piano keyboard and the second shows the notes on the treble clef in standard music notation.
The formula for all major scales for the intervals between notes is W W H W W W H Which can also be written out as whole whole half, whole whole whole half.
You always start on the root note and count that as the first scale degree (# 1). Then you go up the "chromatic scale" (which consists of all notes playable on a piano keyboard) by one whole step to get to the next note in the scale which is the second scale degree. One whole step is equal to two half steps. A half step is represented by each key on a piano keyboard (black keys included).
So in A Major you start on A which is the 1 degree and go one whole step (a black key and a white key) to land on B which is the second scale degree. From B you again go a whole step (one white key and one black key) and you land on a black key which is C#. Next in the major scale formula is a half step because now we are on the first H in our formula W W H W W W H. A half step from C# is to the adjoining key which is a white key and is a D (4th scale degree). This process is repeated (following the whole half formula) until we get back to the root note of A which is the 8th scale degree if you will.
All Major scales will start on the root note as the first scale degree and follow this same formula. A piano keyboard is useful in visualizing the whole (two keys) and half (the next key to the right) steps.
Minor keys have their own formula which differs from the major scale formula.
If you forget this, simply google whatever scale you need to know about and you will find your answer there.
