The Dmadd9 chord contains D, F, A and E, with formula 1–♭3–5–9. Also written Dm(add9), it keeps the minor third F and adds E without a seventh. Compare two root-bass layouts and the two practice tasks.
Build the Dmadd9 chord from D minor plus E. The higher example uses D3–F3–A3–E4; the lower example uses D3–E3–F3–A3. E moves down an octave while the four pitch classes remain the same. The add9/add2 hint describes these examples, not a compulsory spacing rule for every arrangement.
The examples below are complete four-note references. They do not list every omission a performer might make.
Two explicitly authored root-bass spacing examples; this is not a claim that added-note chords cannot be inverted.
For the Dmadd9 chord, Build the chord tones accepts D, F, A and E in any octave. Match this example also checks the specific registers. Correct chord tones in different octaves receive a spacing hint, separating a different voicing from an incorrect note.
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 D3 – F3 – A3 – E4. Then switch to D3 – E3 – F3 – A3. 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.
| Example | Notation hint | Notes, low to high | Bass |
|---|---|---|---|
| Added note higher (9th layout), current selection | Dm(add9) | D3–F3–A3–E4 | D3 |
| Added note lower (2nd layout) | Dm(add2) | D3–E3–F3–A3 | D3 |
Here, the higher layout is labelled Dm(add9); the inside-the-triad layout is shown with the Dm(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.
| Symbol | Notes or formula | Third | Seventh |
|---|---|---|---|
| Dm(add9) | D–F–A–E | Included | Not included |
| Dm9 | 1–♭3–5–♭7–9 | Included | Included |
| Dsus2 | 1–2–5 | Not included | Not included |
Read D, F, A, E as four chord members. The E is the added member; it is not a finger number or a new key signature.
Octave numbers such as C4 locate a register. They are separate from scale degrees and finger numbers.
First choose the four note names in Dm(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.

The reference brings together the formula, both keyboard layouts and their octave labels. Use it beside your keyboard when comparing the two examples.
The Dmadd9 chord diagrams show the selected pitches and octaves without assigning fingers. Both layouts keep D lowest and retain F natural as the minor third. F♯ would change the chord quality rather than only the spacing; the diagram is not a prescribed one-hand stretch.

D, F, A and E. The Dmadd9 chord keeps the minor third F and adds E to D minor. No seventh is included.
The Dmadd9 chord has no seventh. Dm9 includes C natural in its full 1–♭3–5–♭7–9 formula. Adding E to a minor triad and adding it to a minor seventh chord give different complete collections.
No. The Dmadd9 chord includes F as its minor third. Dsus2 uses D, E and A without F. Moving E to another octave does not remove the third from the four-note collection.
The Dmadd9 chord uses F natural. Dadd9 uses F♯, the major third. Both contain D, A and E, so checking the third distinguishes the minor and major added-note chords.
The note names are correct but their octaves differ from the selected example. The note-building task accepts octave differences; the matching task also checks the exact registers.
No. Both supplied examples keep D in the bass and illustrate the placement of E. The lower layout has a Dmadd2 notation hint. Other voicings are possible; no finger numbers or required hand allocation are supplied.
