Happy New Year to you all! As it is the start of the year, now would be a good time to remind you where it all begins, and for those of you new to Music Theory, this is the place to start!

The Major Scale is important because it sets the names of the notes and how we refer to them. It gives us a common language and helps us understand other scales and chords. It also helps us converse with other musicians so that we have a common language.

The Major Scale is made up of a certain sequence of intervals. This sequence is the same for any Major Scale, regardless of the key it is in.

If we now want to describe a different scale, we can refer to the notes in relation to the notes within the Major Scale.

For example:

So, if you know how to spell a scale you can work out what notes are in it by comparing it to the Major Scale.

Let’s change key and use the very popular Minor Pentatonic Scale.
The spelling of this scale is - 1, b3, 4, 5, b7.

If we want to know what notes to play in the key of A:

For A Minor Pentatonic we therefore start on the 1st – an A, then we need a b3, that would make it a C, then the 4th and 5th are the same – D and E, then finally a b7 which is a G.


As you can see, knowing the Major Scale makes learning and working out other scales relatively straightforward. It’s also vital for helping work out chords that you’ve never played or new voicings of chords.

Chords have a similar way of being spelled:

If you know the chord spelling you can work out the notes in any key by reference to the Major scale.

So get those intervals learned, spending time on the Major Scale will help you more than you ever imagined!!
