Well in the forum...there are many threads for how to find chords of songs.. you can take help from them.. Also..if you are talking about sheet music then ....sorry but in the forum we are not using that...I guess(I didn't see that being used anywhere so far). Basically you can first master the rhythm and then see the chords of one of your fav song..and try to change chords at the words mentioned.. Like ..... (DM )Piyu bole(AM) Piya Bole(DM)kyon ye bole(AM) Janu Naa) you can use the rhythm Dhak Chik Chik..(Bass treble trebel) something of that sort..you will know once you play it.. Let us know what exactly you want ....then may be others can also help you...and give some points if it helps you
