9 major chords
The Major 9th (maj9) chord should not be confused with the dominant 9th chord. If we compare Cmaj9 with C9 we could see that the notes changes from C, D, E, B to C, D, E, Bb. It's a relatively uncommon chord, which is probably most used in jazz arrangements. Below you could see this chord played in different tones with a movable shape.

Notice that the chord has some similarities with the 7#9 chord, just two fingers are changing positions.
Since some of the chords above are high up the fretboard and in some situations less suitable, some compliment to maj9 chords in open positions are presented below.

Theory
The only diatonic major 9th chord can be found on the IV degree in a major scale. In C major, this would be Fmaj9 whereas Gmaj9 would be a non-diatonic chord because of the F# note.
Chord formula
The major ninth is built with the formula 1-3-5-7-9 (root, major 3rd, perfect 5th, major 7th and major 9th).

Progressions
Suggestions of chord sequences to try with this chord type:
Dm9 - G13 - Cmaj9
Cmaj9 - C#dim7 - Dm7 - G11
Em - Dmaj9 - Asus2 - Cadd9
Major 9th chords work as I and IV, but not as V chords (atonal). So, for example, in C major key, Cmaj9 and Fmaj9 are viable (diatonic) options.

- B - C - D - E - G (3rd inversion)
- D - E - G - B - C (4th inversion)
