Transposing a song means not playing it in the key it was originally intended but in a key higher or lower than it.
The keyboardists have a TRANSPOSE BUTTON, which they can use to transpose the key to whatever note, and yet play the same keys in the keyboard,
BUT ALAS :(
WE GUITARISTS DO NOT HAVE THIS SUPER FACILITY
NO BUTTONS, NO SYNTHS, NO NOTHING
except a cheap chorus, delay and distortion effect pedal maybe.
You are supposed to play nile nile amber on stage with some singer, and you practice it hard on Dm, and when youre on stage, the singer says
Not Dm today, my voice is ****ed, lets do it C#m (1/2 ket lower)
IF YOU WORKED THE SONG IN OPEN STRINGS -
MAN YOU ARE SCRWD!!!!
The key to not getting caught in any embarassment on stage
is to work songs without using open strings
no open string chords, no open string leads NO
SHIFT into playing into a closed string position
meaning you are not hitting ANY OPEN STRING anytime.
AND TRY LEARN THE SONG with your EYES CLOSED (very important)
and NOW if the singer comes and asks you to shift a key down.
just move your hand one fret down, dont look at the fretboard, and justy play with your eyes closed, imagining that you are in the same scale that you learnt the song.
WORKS WELL, TRY IT
