What does the chord notation X/Y ("slash chord") mean?

TL;DR For pianists, play the X chord with the right hand and the Y bass note with the left hand. For guitar/bass bands: guitarist plays the X chord and bassist plays the Y bass note. (With thanks to @...

Is this an error in this textbook?

The "root" of the problem (so to speak) is that the exercise transcribed the piece incorrectly. The A (edit: in the bass) should actually be an F#. See this score on iMSLP, page 6, the ...

Why is an inverted triad not named as another chord with the first note of the inversion as the root?

This is a fundamental music theory concept: (root position) chords are defined as "stacks of thirds", and inversions are considered to be "the same chord". The notes C-E-G are C ...

Specific chord confusion: why the C# in Eb7 b9 13?

The C# is enharmonically Db, which is the b7 of the Eb7 chord. As for the 9b, it is typical to put the accidental before the chord tone, b9 instead of 9b. Also, the b9 should not be an E but rather an ...

use of 4/2 chord more compelling than root position?

I see at least two reasons: Tonal music is really built on the contrast of consonance and dissonance; the inherent tension and release of that dichotomy is what moves tonal music forward. Your second ...

Em/C: Sound Notation, or Dirty Shorthand?

Who is it meant for, are you writing the notation for jazz players, pop/rock or is it a hymnal or what? Cmaj7 is not that strange, but it's just written communication from people to people, so you are ...

Difference between Edim7 and Gdim7

The chord finder tool is wrong The chord in the Bach in C#dim7. This is because the chord in m. 13 is D minor, and the primary function of C#dim7 is to lead into a D chord (major or minor). This is ...

What should one keep in mind when writing the Neapolitan 6th chord in a chord progression?

Yes, you generally double the 3rd of the chord. It's the chord note that is easier to resolve. Let's take this example in C major, a simple I bii V I: You can see that both the neapolitan chord and V ...

How do you tell the inversion of a diminished 7th chord?

Differentiating inversions All seventh chords, when inverted, contain a second somewhere in the stack of notes. Diminished sevenths are no different. Somewhere in the inversion will be an augmented ...

Why is an inverted triad not named as another chord with the first note of the inversion as the root?

To directly answer the question - why isn't EGC (1st inv. C major) some sort of E chord? It could be. E and G gives an E minor feel to it. Add C calling it B♯, and the chord would be called Em+. A ...

Inversions of chords in closed/open positions

Inversions are always worked out from the bottom note. Thus using a C triad, in close form, C E G is root, E G C is 1st inversion, and G C E is second. That's equivalent to your app's root=0, 1=1st ...

I think you have outlined two of the uses of inversions in your questions already. To add a bass line to the chords that are not just all roots. To put the melody note "up on top" so it is the ...

Do seventh chords have more inversions than triads?

Yes. They have root position, first inversion and second inversion which we have also seen with triads and are exactly the same with the root on the bottom, the 3rd on the bottom, and the 5th on the ...

Are inversions for making bass-lines nice and prolonging functions?

I would argue that there are other uses of inverted chords. One other important usage is for dramatic reasons. A composer may set up a clear upcoming cadence, but at the moment our V chord resolves to ...

This is not possible. PROOF: Given the notes A-C-E-G and no other information, it's impossible to know whether this is a C6 or A-7 chord. Therefore, it cannot be determined whether the chord is in ...

Interval of parallel 5ths in the resolution of a German 6th chord

You are correct that resolving the German 6th to a V results to parallel fifths (Ab + Eb -> G + D). This is one of the rare times where the parallel fifths are allowed. People refer to these specific ...

Unclassifiable second-inversion

We typically classify these chords by what their bass notes do. Thus a passing six-four is so named because the bass functions as a passing note; the same is true for the arpeggiating six-four. Your ...
