This Ab7 piano chord lesson ensures that you are able to understand the chord, use correct fingering, and know the notes to be played.
Knowing chords is one of the essential aspects of playing the piano. There are a great many chords to learn and the best way to learn them is by taking proper lessons.
Trying to look at a book and copying them is OK but are you using the best fingering for the chord. One of the problems with incorrect fingering is that students run out of fingers when playing. This has the effect of their playing being jerky and not smooth at all.
I teach all my students the correct use of fingers and how to play variations on standard fingering where necessary.
