Hey, Not the whole song, but I have figured out the intro of the song. It is a short song so I should be able to knock down the rest some time soon or someone can take it from where I leave off. I played along the original song, not the one covered in Main Hoo Na, and it sounded close to me. I will let you all be the judge. (Am)Chaand mera (Dm)dil, (G)Chaandni ho (C)tum, (C)Chaand se hai (F)dour, (F)Chaandni (Am)kahaa
I do not see any difference between your and my version other than my version being a bit more detailed with more chords incorporated. Then again whatever floats your boat. I have never taken guitar lessons but there is a rule-of-thumb in most, if not all, songs. The song ends on the note at which it starts; the song starts at Am and it should end there. Do not believe me? Try playing the tabs of the song. If you cannot figure them out, then I will post them here for you. Other thing is that there is a loud Dm in that song which shows up later as well which you have left out in your version. That is a matter of personal choice; to play or leave out the Dm. But Am is definitely where the song ends.
Agree with afg_guitarist here. His chords are more exact and correct. The Dm is spot-on, and chandni kahaan does end with Am.
