welcome to IGT hari. there are millions of videos on youtube and over the internet., view them, get ur interest more,, find a good music school near ur place or if u r interested to teach urself get some DVDs! ;-) above all the main thing is ur commitment.. all the best.
Hii I am Danish.... I really need help with the strumming pattern and i need a finishing touch with the chords... they dont sound that good in my case....
make sure whatever chord you hold sounds clean,. practice them with just down strokes and then later up! and make up and down., practice till u get a clean sound. till that dont go for any song's strumming patterns which are too complicated., tune ur ears to understand what is actually played on strumming. how it sounds when its up or down, whole, half quarter, muted, etc., i love playing rhythm guitars! ;-)
