Thought i might as well post it here

Try this..
this is how i learnt to pick up strumming patterns..

play the chord using continuous up and down strums.
ie.- ^v^v^v^v

match it to the beat according to the song (2/4, 3/4 or 4/4).. one up and down strum per beat..

Try not to go out of beat..

then try to figure out the pattern by strumming on some of the beats and leaving some of them empty..

for example, practice these..go in order ( v-down strum, ^-up strum, - :dont strum).. Again, remember, each v,^ or - indicate half a beat..

v- v- v- v-

v- v^ v- v-

v^ v- v^ v-

v^ v^ v^ v-

v^ v^ v^ v^

v- -^ -^ v-

v- v^ -^ v^

v- -^ -^ v-

Note - Remember, the most important thing is to move your strumming hand even when you're not not strumming on a particular beat.. the hand movement should continue in a regular up and down pattern

finally try some of these patterns.. they work with most hindi songs..

v- v^ -^ v^ : This one is called twist

v- -^ -- v- : This one is called keharwa (Ya, it's the same as the keharwa taal in tabla which is used in most hindi songs)
