I'm sure I play some of those 5ths 7ths and maybe 9ths, but I wouldn't know because I don't read music and rarely know what chords I play. I just play what sounds good to me. Perhaps someone could tell my what kind of chord I'm playing in the 3rd song on my profile "long way home". At about 15 seconds I play softer to make less distortion and you can hear the chord clearly there. I can tell you it is a g based bar chord.
I got a chance to try the Bm7 with the D chord, RhythmMan. It sounds very good, it has a great flow. It actually sounds better using a Dsus2 with the Bm7. I usually will take chords like these and turn them into arpeggios.
Like this for instance:
------------------------------7-------------------0----2--------------------------0--------
-----------------------7--------7---------3--------3----3--------------3--------3--------
-----------------7-------7-------------------2--------------------0-------0-----0--------
-----------7-------7-------------------0----------------------------2------------2--------
---------------9------------------------------------------------3-----------------3---------
-------7-------------------------------------------------------------------------------------
A Bm7 arpeggio, followed by a Dsus2/D arpeggio, and then a C add9 arpeggio, and finally the C add9 chord strummed once itself.
Just made that pattern up. Sounds good. Thanks for the suggestion of the Bm7 and D chords, RhythmMan.
Peace out, GuitarAnatomy.
