I would strongly advise you not to go out with a guitar :)
It depends on what you define as a chord.
Taking only major and minor chords, there are 24 possible chords, in 3 inversions at varying positions up the neck (barre chords) as well as a number of open chords. A conservative estimate would be 100 "simple" chords.
Opening up, and allowing jazzier chords (sevenths, ninths, fourths etc.) provides a multiplicity of possible chords.
In short, there are a wide variety of combinations of notes you can play on guitar, together, that form a chord.
The trick is finding the right one.
He uses a broken pedal (for brass instruments) called "the Maestro."
According to this site :
the lower pitch string is be tuned to a C and the higher pitch to the G above.
the strings on a guitar are
If you are a beginner here is a saying that helped me
ok so i hope i helped with that part now the actual notes are
B5 wich is b flat nd is the way i write it but it actually Bb
I hoped i helped for the 12 note scale and oh and #=sharp and b is flat. and every note has a # or b except for B,C AND E,F.
so the 12 note scale starts on the 1st frett on the E strings and is and F
2nd frett F#
3RD FRETT G
4TH FRETT G#
5TH FRETT A
6TH FRETT Bb
7TH FRETT B
8TH FRETT C
9TH FRETT C#
10TH FRETT D
11TH FRETT Eb
12th frett E
THEN IT REPAETS FROM WHAT WE STARTED WITH AN F NOTE ON THE 1ST FRETT THEN 13 - 24 (DEPENDING ON YOUR GUITAR) REPEATS THE NOTES ALL OVER AGAIN.
AND THERE YOU GO THOSE ARE ALL THE NOTES SO IF YOU MEMORIZE THOSE YOU KNOW ALL THE NOTES ON THE GUITAR.
