My challenge is to stop getting lost as to which measure to go to in certain notation and rhythm chord charts. After the repeat sign, repeat to what measure? D.S., Coda, and where to go after the 1st, 2nd and other commonly used symbols are slowing me down and I am relying on guesswork and the vocals (when I can hear them) to get me back to where I should be. Chromaticism and familiarity with the piece (as well as a competent and understanding pianist) has been my very good friend on too many occasions in the more complex pieces. Help!?
