Ok, couple of questions on chord names.

I know triads of the shape:

5 1 3
3 5 1
1 3 5

Are known as root postion, 1st inversion and 2nd inversion

But do the following forms have names?

3 5 1
5 1 3
1 3 5

I personally use these all the time, but have no idea if they have a proper name.

Another question has to do with quartile harmony. How are non-tertiary harmonic structures such as the following named?

9
7
4
1

Piece of cake, King.

1. Inversions are named by the bass note. 1-3-5 is a 'closed root position' triad, and 1-5-3 is an 'open root position' triad. The same applies to the other intervals - inversion number is determined by the bass note, regardless of what happens above it.

2. Quartal harmony is named according to standard tertian naming, since we don't want to inadvertantly have two different names for the same chord. So 1-4-7-9 is simply called maj9sus. Although that name technically includes a fifth, it's like our 11th chord thread - you'd rarely play a fifth in a maj9sus chord.

I normally use 1-4-7-b3 (say, C-F-Bb-Eb, or x3334x), though I've used quartal harmony more on piano than on guitar. Small article here:
