These three diagrams illustrate the root position (1 b3 5), first inversion ( b3 5 1), and second inversion (5 1 b3) of the Cm chord.
The following example uses the root position, first inversion, second inversion, and an octave of the root position of the Cm chord. Use the fingering shown in the diagrams but be prepared for fingering variations depending on where the music is going.
Here is a keyboard part making use of the first inversion of the C minor chord. Notice the interplay between the two hands in this part.
Here are some keyboard parts which make use of the C minor chord in various inversions. If you have trouble co-ordinating both hands, practice each hand separately at first and count as you play.
This one uses a slash chord (F/C) in the second bar. Listen to how effective this sounds when played over the left hand part.
Slash chords do not always have to be written above the music for you to play them. E.g. the following example has a Cm chord symbol above it, but the right hand plays an F chord on the second half of the first beat. Because the part immediately returns to Cm, it is not necessary to write F/C for half a beat. This is common in keyboard playing.
