Hi in the tutorial My Sweet Lord easy version Caren uses this strum pattern

for the Em and for the A

DDDUD UUDDUDU

In the advanced version with Mike it is the same chords but with this strum variation

For the Em and for the A

DDDUD UDUDDUD

Does it matter which variation I use If I strum using Carens version will I have to change it later on I am just working on the strum now

Thank You
