D♭m(add9) Piano Chord

Use D♭, F♭, A♭, E♭. The formula is 1–♭3–5–9. Keep the F♭ third: removing it changes the note collection to a suspended shape.

The list above names the chord members. For a specific register, read the octave numbers on the selected example below.

Start with D♭3 – F♭3 – A♭3 – E♭4. Then switch to D♭3 – E♭3 – F♭3 – A♭3. The E♭ moves down one octave while the other three notes stay in place.

Both examples keep D♭ as the lowest note. This comparison changes spacing, not the bass. It is a pair of reference examples, not a complete inversion catalogue.

Here, the higher layout is labelled D♭m(add9); the inside-the-triad layout is shown with the D♭m(add2) notation hint. This follows the textbook illustration, not a claim that every player uses the labels identically.

Musicca also lists add2 as an alternative add9 label. For an exact arrangement, use the written pitches or score. For a note-identification exercise, separate the chord members from their octaves.

This page's complete added-note examples include the third and no seventh. A ninth-chord formula includes a seventh; a sus2 collection omits the third. Compare the note lists, not just the number 9 in a symbol.

This formula needs F♭ (the E key). The displayed letter names follow the degree spelling; the keyboard highlight follows the sounding pitch.

Octave numbers such as C4 locate a register. They are separate from scale degrees and finger numbers.

First choose the four note names in D♭m(add9), in any octave. Next select Match this example and reproduce the specific notes displayed. Correct chord tones in different octaves should receive a spacing hint, not a message that the chord itself is wrong.

These browser exercises check your selection on this page, not a performance on an acoustic piano. Fingerings are not supplied; the diagrams are not a prescribed one-hand stretch.

The reference brings together the formula, both keyboard layouts and their octave labels. Use it beside your keyboard when comparing the two examples.
