The chord CEA represents an A minor chord in first inversion.
Understanding the CEA Chord
When you play the notes C, E, and A together, you create a chord. This specific arrangement represents an A minor chord, but it's important to understand why and the significance of its inversion.
Root Position vs. Inversion
- Root Position: A minor in root position would be A - C - E. The root note (A) is the lowest note.
- First Inversion: In a first inversion, the second note in the triad (C) is moved to the lowest position of the chord. This is not the case with CEA. The third, A, is in the lowest position.
- Second Inversion: In a second inversion, the third note in the triad (E) is moved to the lowest position of the chord. This is not the case with CEA.
The "CEA" Arrangement
In the CEA arrangement, the A is in the tonic position, C is a minor third above it, and E is a perfect fifth above A. The C is in the bass position, so this is first inversion, which places the third (C) of the A minor chord at the bass position.
Why It Matters
Recognizing chord inversions is crucial for:
- Smooth Voice Leading: Inversions help create smoother transitions between chords in a progression.
- Bass Line Variation: They allow for more interesting and varied bass lines.
- Harmonic Color: Inversions can slightly alter the overall sound and feel of a chord.
In conclusion, the notes C-E-A form an A minor chord in first inversion, as it is C that is in the bass position.
