The only dumb quest. is the one that has'nt been asked.
A progression is the way chords proceed one to the next.
an example would be --in the key of "c" the first chord would be Cmajor
the forth would be Fmajor (C ...(d..e..) F)/
so, if someone said to play a one , four, one ( I,IV,I) in the key of C.
You would play cmag, fmag, and back to cmag.------get it?
