Relationship between hand and keyboard about Chords
Any polyphonic instrument is capable of reproducing the complete orchestra.
Considering left hand chords, the fifth finger plays the bass parts, the 4, 2, 1 plays the harmonic trend – Major, Minor, 7th, etc…i.e. guitar, brass, cellos, etc… and the 2, and 1, can play the alternating bass or/and the off-beat.
Any score of any music is just a string of more or less complex chords with passing notes that make the transition from one chord to another.
How not to get lost in learning chords on the keyboard ???
Because the keyboard was designed in relation to the morphology of the hand, there is a SINGLE position which allows you to practice all the chords of the same type very easily.——–It is the Root position:
C = DO MI SOL DO C-E-G-C 5 4 2 1
Note: For the Electone or the organ, the work of the 5, the 2 and the 1 will be done with the feet, thus freeing the left hand for a more lyrical and counterpoint playing.
Similarly to the organ, you will need to build into your hands those invariable spaces between the fingers that will allow you to move without error on the keyboard.

C chord F chord G chord



Exactly the same position !!!
little finger and thumb are the guides
The secret is not to move the fingers between them and move the blocked position!!!
and then, just articulate your musical phrase.
