ummmm... Practice...
also try transposing your piano and sax to the frets...
easier said than done but that depends in how good you actually are in those...
that may give you a starting point, thought...

That's how I learned. I transposed trumpet and piano music to the frets. Just be sure to remember that your sax is Eb (the Bb trumpet thing gave me trouble when I started this around the 6th grade.)

Another thing that I did that REALLY helped was I would draw a diagram of the fretboard, and fill in each fret with the note name. Other kids doodled pictures of airplanes and cars on their notebooks...I had about a million fretboards ;) Kept my grades low but the end result is I can look at a fretted note and tell you the name of it...anywhere on the fretboard.

That helps a BUNCH when you get into the theory side of the instrument.

Good luck!

Practice all the time. Period.

You know...I learnt most of my stuff from the net....scales, chords etc etc, yes u do need a teacher for all the questions u may have......then again u can simply ask us here...

I practice as much as I possible can, but it's what should practice over and over again to improve my skills, that I am not sure on.

actually thats how im learning how to play a piano... just finding stuff on the guitar and finding the note on the piano, i can now play the intro to november rain :)... lessons??? you can prolly find some stuff on this site or on the internet somewhere, theres a whole resource out there... you just gotta kno where to look

See if you can mind a mentor to play with. That's what I did. I guy I worked with plays and we still jam together. It's great fun and you learn heaps.
