A major mode can be thought of as a way of manipulating the notes of a major or diatonic scale in order to generate a greater variety of sounds.
This is basically another name for the term scale.

5. Music: Modes
Modality
This term refers to the different ways we center and organize the use of our diatonic scales.
Examples Major Mode
Appalachian Springs CD 6 Tr. 15
Rent CD 1 2:13 into Tr. 23
Example Minor Mode
Erlkonig CD 3 Tr 22
Sym. # 1 CD 5 Tr. 5
A list of procedures and steps, or a lecture slide with media.

6. Music: Keys
Keys
In music a key is the major or minor scale around which a piece of music revolves. A song in a major key is based on a major scale. A song in a minor key is based on a minor scale.
A song played in the ‘key of C major’ revolves around the seven notes of the C major scale – C, D, E, F, G, A, and B. That means the fundamental notes making up the song’s melody, chords, and bassline are all derived from that group of notes.
Conclusion to course, lecture, et al.
Similarly, a piece of music can be in a minor key and revolve around a natural minor scale. For example, a song in the ‘key of D minor’ uses the notes of the D minor scale – D, E, F, G, A, Bb, and C.

7. Music: Modulation Modulation Example Alexander Nevsky CD 5 Tr. 36-37
This aspect of music is most commonly the act or process of changing from one key (tonic, or tonal center) to another.
