Learn The A Major Scale

The A major Scale is good for acoustic guitars because of the E, A, D and B open strings belonging to the scale. It has three sharps in it the F, C and G notes.

The Open Strings

The open string notes are the 6th string E=5, the 5th string A=root, the 4th string D=4th, the 2nd string B=2/9 and the 1st string E=5. The numbers after the notes tell you what scale degree they are. Check below for more detail on numbering.

These are notes that can be used freely in the A scale. They normally won’t clash with any other scale tones.

A Major Scale Numbering

All the major scales have numbers that go with the notes for easy identification. You will find out later that this way of referring to numbers makes it possible to refer to all scales and chords no matter what key you are in.

This also refers to chords built from scales. When referring to chords the numbers are written in Roman numerals, upper case for major chords and lower case for minor chords.

This is how the beginning bar in sheet music will look if you are in the key of A. The sharp symbol is over the F line and the C and G spaces in the music staff.

This doesn’t mean the music won’t have other flats or sharps in it. They will be marked in the music itself. This means every note in the F, C and G position in the music staff will be sharp.

This helps keep the music easier to read as you get more flats or sharps in a key.
