There are some keyboards (e.g. Yamaha) upon which the auto (Single Finger) Chords will produce the correct sound (for the harmony) no matter what inversion you play the chord in. Is this where you are getting confused?

I would refer to those inversions as C, C/E, C/G... is this not international standard?

you need not feel confused because C,E,G OR E,C,G OR GEC ALL ARE SAME .BYE ABINOAM RONG

G C E: C major in 2nd inversion C E G: C major in root position E G C: C major in 1st inversion They are all C major. They all use the notes that builds thirds on the C major scale. The only difference is the order of the notes. One learns about this in the rudiments of music.

So which one is `correct` to play? Both books are referring to the chord as C major. But G| | |C| |E and C| |E| |G make two different sounds so they can`t both be C Major.

What you`re being confused with is the inversion of chords. Every three note chord has a root and 2 inversions as follows (for C major) C E G E G C G C E you take the bottom note and put it on the top. The fingering for each inversion is different. For most size hands the most comfortable fingering is C E G 1 3 5 E G C 1 2 5 G C E 1 3 5 1=THUMB 2=INDEX etc... write back if there is any confusion
