Open Music Theory / Chelsey Hamm — Introduction to Diatonic Modes and the Chromatic Scale
Seven modal interval patterns and parallel relationships Chromatic half steps and non-mandatory ascending-sharp / descending-flat spelling
Learn the seven diatonic modes and compare how their note patterns differ. Use the C examples below to see, hear and practice each mode.
Each row keeps C as the tonic so the seven mode patterns can be compared side by side. The last C repeats the tonic one octave higher.

A mode is more than a new starting label. The seven diatonic modes have different arrangements of whole and half steps. Keeping C as the tonic makes those differences easier to compare: the first and last note stay C while selected notes inside the octave change. The table gives one complete C example for every mode.
Compare C Ionian with C Lydian: F becomes F-sharp. Compare Ionian with Mixolydian: B becomes B-flat. Within the minor group, C Dorian uses A-natural where C Aeolian uses A-flat. C Phrygian also lowers D to D-flat; C Locrian lowers G to G-flat as well. Read each note list before playing so the altered notes remain visible.
Parallel examples share C as their tonic. Relative examples share a pitch collection but have different tonal centers. For instance, C Dorian and B-flat major use the same pitch classes. That relationship helps identify notes; it does not establish that a passage is in C Dorian simply because those notes appear.
Play C Ionian, then C Lydian. Pause on F and F-sharp and return to C after each example. Next compare the A-flat in C Aeolian with the A-natural in C Dorian. Keep the comparison short and use the note lists as your check.
The examples keep C as tonic. C Ionian: C–D–E–F–G–A–B–C; C Dorian: C–D–Eb–F–G–A–Bb–C; C Phrygian: C–Db–Eb–F–G–Ab–Bb–C; C Lydian: C–D–E–F#–G–A–B–C; C Mixolydian: C–D–E–F–G–A–Bb–C; C Aeolian: C–D–Eb–F–G–Ab–Bb–C; C Locrian: C–Db–Eb–F–Gb–Ab–Bb–C. The last C repeats the tonic one octave higher.
Compared with major (Ionian), Dorian lowers 3 and 7; Phrygian lowers 2, 3, 6 and 7; Lydian raises 4; Mixolydian lowers 7; Aeolian lowers 3, 6 and 7; Locrian lowers 2, 3, 5, 6 and 7. These are comparisons to the same tonic, not to each mode’s relative major.
