1. What is 7th Chord Inversion?

7th chord inversion refers to rearranging the notes of a seventh chord so that a note other than the root is in the bass position. This creates different voicings while maintaining the same harmonic function.

2. How Does the Calculator Work?

The calculator uses the following inversion rules:

Where:

• Root Position (0): Root - Third - Fifth - Seventh
• First Inversion (1): Third - Fifth - Seventh - Root
• Second Inversion (2): Fifth - Seventh - Root - Third
• Third Inversion (3): Seventh - Root - Third - Fifth

3. Importance of Chord Inversions

Details: Inversions create smoother voice leading, add variety to harmonic progressions, and allow for different bass movements while maintaining the same harmonic function.

4. Using the Calculator

Tips: Enter the four notes of your 7th chord (root, third, fifth, seventh) and select the desired inversion. The calculator will rearrange the notes accordingly.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between inversions and voicings?
A: Inversions specifically refer to which chord tone is in the bass, while voicings refer to how all chord tones are arranged across all voices.

Q2: Do inversions change the chord's function?
A: No, inversions maintain the same harmonic function but can affect the chord's stability and voice leading.

Q3: How do I notate chord inversions?
A: Inversions are typically notated with figured bass symbols (7 for root position, 6/5 for first inversion, 4/3 for second inversion, 4/2 for third inversion).

Q4: Are all inversions equally common?
A: No - first and second inversions are most common in classical music, while jazz uses all inversions more freely.

Q5: Can I use this for extended chords?
A: This calculator is specifically for 7th chords. Extended chords (9th, 11th, 13th) have more possible inversions.
