When writing an Augmented chord, which inversion of the chord should I use?
The problem came up while I was composing (piano). I came to an augmented chord and couldn't think of which version to use due to the accidentals.
The key I was writing for here is C# Minor. 'n' reperesents a natural:
1. G#+ Root: G♯ - B♯ - D♯♯
2. C+ 2nd Inv: G♯ - C♮ - E
3. E+ 1st Inv: G♯ - B# - E
I remember from my music theory that an inverted augmented chord creates another augmented chord. But I have no clue how I should write it. If I had to guess, I would say that you chose based off the key that you're writing in.
You use the one nearest to the chord progression. ... C - E - G = C - E flat - F# (and usually adds the note "A" for the doubly diminished 7th. ... C - E - G = C - E G# ... I love them; they make transitions and resolutions so rich. They're used all the time. They're great for VOICE-LEADING. And they only have the two inversions Music theory uses a lot of ENHARMONICS when naming intervals, a lowered diminished interval is a doubly diminished interval (e.g. "Coo") and a raised augmented interval is a doubly augmented interval (e.g. "C+").
You are right if you play any version of an augmented triad, you get another augmented triad or chord. So I would say is pay attention to the movement of the bass, what chord precedes it and what chord comes after it. Whatever bass note would make the smoothest transition to the bass note of the adjacent chords would be a good pick. From that you could choose any of the inversions.
