dorian mode

The Solution below shows the dorian mode notes on the piano, treble clef and bass clef.

The Lesson steps then explain how to identify the mode note interval positions, choose note names and scale degree names.

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

Solution - 2 parts

1. dorian mode

The dorian mode has no sharp or flat notes.

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.

On the bass clef, Middle C is shown with an orange ledger line above the main 5 staff lines.

2. dorian mode descending

Lesson steps

1. Piano key note names

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. dorian mode tonic note and one octave of notes

The numbered notes are those that might be used when building this mode.

The dorian mode always starts on note D(when not transposed to another key).

Since this mode begins with note D, it is certain that notes 1 and 13 will be used in this mode.

Note 1 is the tonic note - the starting note - D, and note 13 is the same note name but one octave higher.

3. dorian mode note interval positions

In their simplest / untransposed form, modes do not contain any sharp or flat notes.

This can be seen by looking at the Mode table showing all mode names with only white / natural notes used.

The dorian mode uses the  W-H-W-W-W-H-W  note counting rule to identify the note positions of 7 natural white notes starting from note D.

To count up a Whole tone, count up by two physical piano keys, either white or black.

To count up a Half-tone (semitone), count up from the last note up by one physical piano key, either white or black.

The tonic note (shown as *) is the starting point and is always the 1st note in the mode.

All notes in this mode are natural whites (ie. no sharps or flats), which mean that this mode has not been transposed into a different key.

4. dorian mode descending

For all modes, the notes names when descending are just the reverse of the ascending names.

So assuming octave note 8 has been played in the step above, the notes now descend back to the tonic.

5. dorian mode degrees

Scale degree names 1,2,3,4,5,6, and 8 below are always the same for all modes (ie. 1st note is always tonic, 2nd is supertonic etc.) , but obviously the note names will be different for each mode / key combination.

In this mode, the 7th note is called the subtonic, and it has a whole tone (two semi-tones, two notes on the piano keyboard) between the 7th and 8th notes.

In contrast, for example, the lydian mode has only one semitone / half-tone separating the 7th and 8th notes, and in this case the Seventh note is called the leading note or leading tone, as the 7th note feels like it wants to resolve and finish at the octave note, when all mode notes are played in sequence.

The modes that have a subtonic as the 7th note are dorian mode, phrygian mode, mixolydian mode, aeolian mode and the locrian mode.
