MAJOR 9TH

A Major 9th chord is a group of harmonic notes that has a very complete sound.  And this chord should sound complete - since it has 5 notes.  It begins with a common Major chord, and then not only adds the ninth note of the scale to that chord, but also a dominant 7th note (flatted 7th) to it.  To determine which notes are to be used for this chord, let us look at a scale.  We will use a scale in the key of C to show how this chord is put together:

Scale in Key of C

Notes C D E F G A B C D E F G A B C    
Number 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15    

A scale in the key of C shown above are the normal notes that one might expect in a song.  Instead of calling the notes C, D, E, etc.  or 1, 2, 3 , we also could think of the sequence as the singing notes: do, re, me fa, so, la ti do.

Chromatic Scale starting with C

Notes C C# D Eb E F F# G G# A Bb B C C# D    
Number 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15    

A chromatic scale is all of the possible musical notes - and not just the notes in the C scale.  Note that between two "whole steps" such as C to D, that there is a "half step" in between, that we could call C# (C sharp) or we could also call Db (D flat).  Note that C# and Db are the same note, and could be called by either name.  Basically, one half step down from D is the same as one half step up from C.

In this case, a Major 9th chord is made up of the 1st, 3rd 5th, dominant 7th (flatted 7th) and 9th  notes of the scale.  For a C Major 9th chord then (key of C), the notes of this chord would be:  C, E, G, Bb and D.  This chord would be abbreviated:  CM9

If you have some instrument skills, particularly with a keyboard instrument such as piano, organ, accordion, or keyboard itself or similar, you can do multiple track recording and create you own band recording of perhaps 4 or 8 or 16 or more pieces. This book focuses on music theory on help for determining what some of those other band parts might play, such as strings, bass or other instruments.
