Hi Everyone,

When I'm following a chord progression playing, generally, roots and 5ths in a I; IV; V or a bit more and I suddenly get to an A7 or D7, in addition to the root, does it mean that I can/should play the 7th note of the major scale and it will work?

A Major 7th won't sound too pretty over those chords.

A7 = A Dominant 7, you flatten the Major 7th a semitone to get the Dominant (flattened) 7. Basically a Major chord with a b7.

Play the chord on bass and check out the difference in the 7:

Root - C
Major 3rd - E
Dominant 7 - Bb

If it reads A7 the Mixolydian mode fits right over it 90% of the time. If not you can just run through the Chord Tones. The major 3rd and the Minor 7th.

The correct 7 sure, help yourself.

Major Scale Box.

G|---2---|-------|---3---|---4---| 1st string
D|---6---|-------|---7---|---8---|
A|---3---|---4---|-------|---5---|
E|-------|---R---|-------|---2---|4th string

Basic Chords
Major Triad = R-3-5, aka C
Minor Triad = R-b3-5, aka Cm
Diminished Chord = R-b3-b5. aka Cdim

7th Chords
Maj7 = R-3-5-7, aka Cmaj7
Minor 7 = R-b3-5-b7, aka Cm7
Dominant 7 = R-3-5-b7, aka C7
½ diminished = R-b3-b5-b7, aka Cm7b5
Full diminished = R-b3-b5-bb7 You will very seldom run across this chord - not sure how it would be listed.

Scales
Major Scale = R-2-3-4-5-6-7 Get the major scale into muscle memory - want the major pentatonic........
Major Pentatonic = R-2-3-5-6 leave out the 4 and 7.
Natural Minor Scale = R-2-b3-4-5-b6-b7 Major scale with the 3, 6 & 7 flatted. Major scale's pattern is home bass for major scales and the Natural minor scale's pattern is home bass for the minor scales.
Minor Pentatonic = R-b3-4-5-b7 Natural minor scale with out the 2 and 6
Blues = R-b3-4-b5-5-b7 Minor pentatonic with the blue note (b5) added
Harmonic Minor Scale = R-2-b3-4-5-b6-7 Natural minor scale with a natural 7.
Melodic Minor Scale = R-2-b3-4-5-6-7 Natural minor scale with just the b3, or think of it as a Major scale with a b3.

Generic Notes.
The root, five and eight are generic and fit most any chord. Remember the diminished has a flatted 5. What is the 8? Another root one octave higher.
The 3 is generic to all major chords. See a major chord R-3-5-8 is going to work.
The b3 is generic to all minor chords. See a minor chord R-b3-5-8 will also work.
The 7 is generic to all maj7 chords. Cmaj7 for example = R-3-5-7.
The b7 is generic to all dominant seventh and minor seventh chords. C7 = R-3-5-b7 and Cm7 = R-b3-5-b7
The 6 is neutral and adds color, help yourself to 6’s. Love 6's with major chords R-3-5-6 has a great sound.
The 2 and 4 make good passing notes. Don’t linger on them or stop on them, keep them passing.
In making your bass line help yourself to those notes, just use them correctly.
Roots, fives, eights and the correct 3 and 7 will play a lot of bass.


Put as much of this into muscle memory as you think you will be running into. Run your scales so your fingers know where to go and your ear can recognize the good notes from the bad ones. Run your chord tones like you do you scales - see a Cmaj7 chord and your fingers know right away what to do.

Depending on the song just roots may be enough for this specific song. If you feel you could add more look for the 8, need more look for the 5, need more - help yourself to as many of the chord tones as you can handle with out the music going off and leaving you. http://www.youtube.com/watch?v=R4x0u...eature=related Autumn Leaves will have some measure with two chords in them. All the room you have will be two notes per chord, which two? Up to you. Autumn Leaves will take some time, keep plugging. Now here is something a little easier....................

Here is "Mary did you know". http://www.musicnotes.com/sheetmusic...?ppn=MN0048391
Scroll the screen down just a little...... The bass line is just R's, 5's and 8's.

Have fun.

on the 5 chord - you can play the 7th note of the tonic key major scale.

IE if you are in D major and you have an A7 chord you can play the 7th note of D major which is C# - this is the 3rd degree of the A7 chord!

Learn basic harmony and you'll know this for all chords.

A major chord is 1, 3, 5 so C is C E G
A minor chord is 1, b3, 5 so Cmin is C Eb G
A 7th chord is 1, 3, 5, b7, so C7 is C E G Bb
A Major 7 is 1, 3, 5, 7 so CMaj7 is C E G B
A minor 7 is 1, b3, 5, b7, so Cmin7 is C Eb G Bb
A diminished is 1, b3, b5, bb7 so Cº is C Eb, Gb Bbb (same note enharmonicaly as A, but the correct name in this situation is "B double flat")
An augmented chord is 1, 3, #5 so C+ is C E G#

Learn these, and learn how to build these seven types of chords starting on any root, and you'll know more than most people talking modes know.

The Major 7th can work over a Dominant chord as a passing tone played on an "up" beat. 1, 2, 3 & 4 are down (accented) beats, an upbeat is an unaccented beat preceding an accented beat.

The Dom7 BeBop scale = root, M2, M3, P4, P5, M6, m7, M7, [octave]. Chord tones are in bold.

The Major 7 note becomes a chromatic passing tone leading from the m7 up to the octave, or from the root down to the m7. Since the root, octave and m7 are two of the four chord tones in a Dom7 chord, these are your best bet for "downbeat" notes.
Play a Dom7 chord on a keyboard, sustain it, grab your bass and play this little run up & down; m7, M7, root, M7, m7. It's a fairly common sound. Just needs a TLC in it's usage
