# D-double-flat note

The Solution below shows the position of note D-double-flat on the piano, treble clef and bass clef.

The Lesson steps then describe the note characteristics and relationship with the notes around it, and also lists which scales the note is in.

For a quick summary of this topic, have a look at Note name.

## Solution

### 1. D-double-flat note

This step shows note D-double-flat on two octaves, on the piano, treble clef and bass clef.

Dbb is a white key on the piano.

Another name for Dbb is C, which has the same note pitch / sound, which means that the two note names are enharmonic to each other.

It is called double-flat because it is 2 half-tone(s) / semitone(s) down from the white note after which is is named - note D. Middle C (midi note 60) is shown with an orange line under the 2nd note on the piano diagram.

These note names are shown below on the treble clef followed by the bass clef.  ## Lesson steps

### 1. Piano key note names

This step shows the white and black note names on a piano keyboard so that the note names are familiar for later steps, and to show that the note names start repeating themselves after 12 notes.

The white keys are named using the alphabetic letters A, B, C, D, E, F, and G, which is a pattern that repeats up the piano keyboard.

Every white or black key could have a flat(b) or sharp(#) accidental name, depending on how that note is used. In a later step, if sharp or flat notes are used, the exact accidental names will be chosen. The audio files below play every note shown on the piano above, so middle C (marked with an orange line at the bottom) is the 2nd note heard.

### 2. D-double-flat note

This step shows note D-double-flat in two different positions on the piano, and describes the note characteristics.

Dbb is a white key on the piano.

Another name for Dbb is C, which has the same note pitch / sound, which means that the two note names are enharmonic to each other.

It is called double-flat because it is 2 half-tone(s) / semitone(s) down from the white note after which is is named - note D.

The next note up from Dbb is Db / C#.

Or put another way, Db / C# is 1 half-tone / semitone higher than Dbb.

The next note down from Dbb is B.

Or put another way, B is 1 half-tone / semitone lower than Dbb.

There are no black keys between Dbb and B. ### 3. Note D-double-flat is found in which scales ?
