I appreciate the initial simple chords lessons are pretty mundane material, so if you choose to move on to the next lessons in the early stages, then just remember to keep practising the previous lesson material in conjunction with it until you achieve a level of demonstrated competency expected of the 'play along with Lisa' melodies.

[br]As a general guide to Fundamentals One lessons.

IME&O you don't have to play them perfectly by lesson end at any single viewing, but my take is that you should be comfortable with playing the chords and making the chord changes at tempo along with the melody consistently [u]most of the time [/u]before you move on to a new lesson.

Occasional errors are OK. You'll work them out over time.

Why? Guitar is a doing thing/tactile skill, not just a knowing thing/mental knowledge. Because as you move on you'll be building upon what you learnt previously and using it in conjunction with new material. You only want to have to focus on the new material without being encumbered by not being able to perform to standard something the next lesson expects you can with a level of competency.

[br]The main thing. Enjoy the learning process.

[br]All the best with it.
