I like to associate a song with each sound (similar to the way Barbara learned intervals.)

****************************

Ionian Mode is called the "natural major" mode. Many traditional American songs you can sing or hum are 'natural major' tunes.

Aeolian mode is called the "natural minor" mode. Many traditional Scottish and Irish tunes sound good in this 'weeping and wailing' mode. Wayfaring Stranger, Good King Wenceslas, and Shady Grove/Mattie Groves are the best known Aeolian songs.

Mixolydian mode is only "slightly minor", and is used extensively for neo-celtic music, Irish fiddle tunes, and the masterpieces of Turlough O'Carolan.

Dorian mode is not so minor sounding as Aeolian mode, but more so than Mixolydian. Barbara Allen, Scarborough Fair, and Greensleeves are well known Dorian tunes.
