Chord extensions are where extra 3rds are stacked on top of a triad to produce 7ths, 9ths, 11ths and 13ths.

Lesson 2 - key signatures and the circle of fifths

Key signatures tell you which key the music is in.
Circle of fifths in music theory, the circle of fifths (or circle of fourths) is the relationship among the 12 tones of the chromatic scale, their corresponding key signatures, and the associated major and minor keys.
