reading is VERY important if you are trying to grow and perfect your craft to be the best you can be! I ask all musicians this question when they ask me this. How far would you make it in basketball if i put you on a court with no basketball knowledge other than what you watched other people do? well you might turn out ok, but you wouldnt be a coaches choice to play very often and why?? Because you wouldnt know plays, defensive sytems, offensive systems you would be blind to a whole punch of other knowledge needed to to be an affective player. same goes for music it is not just important to know what you played, but it ismore important to know WHY you played what you played. Why that chord should go there, why that run fits that scale. THats why most musicians hear jazz and they freak out, because to play jazz its 80% knowledge you have to know why and when to play certain things. Gospel is one big repetative pattern we play the same chords, runs passes in everything! you ever notice that no matter what city you hear a different musician in, we all at somepoint play most of the same chords?? because 90% of gospel musicians play by ear, they play what they heard other people play. If you want to really advance the truth is you need both. I started playing by ear of course then i took formal piano lessons, then i started studying jazz in college, and most of the gigs i get outside of church, requires that you at least be able to read charts, its only so far your ear will take you but knowing music will help you alot further. Wouldnt it be easier , while trying to learn a difficult song by ear, with your ear glued to the radio or Cd trying to hear the chords and passes, wouldnt it be easier to just pick up the sheet chart and just learn it that way, i promise it will save you a bunch of time and headache, although your ear is very important you need to understand music to grow PERIOD!! good luck and you playing and may God grant you increase
