Don't know the technical aspects of music enough to understand what is going on here. Would like examples from real songs to illustrate.

- yodsanklai 12y agoMost songs are based on chord progressions (a sequence of several chords) that is repeated through the whole song. More precisely, there maybe different chord progressions within a given song. For instance, one per section (intro, verse, bridge, chorus, outro and so on...). In theory, there are tons of possible chord progressions but not all of them sound good. In practice some are extremely common (like I - IV - V in rock or ii - V - I in jazz) and can be shared across very different genres. Google "common chord progressions" for many examples. Now for the numbering system. Chord progressions can be described as a sequence of numbers that define the chords in a relative way (in CS terms, think of a relative path in a file system VS an absolute path). In music, what is important to the listener ear is the relation between the notes, not so much the absolute pitch of those notes. Example : A - D - E and E - A - B are the same progressions (I - IV - V) in the key of A for the first one, and in the key of E for the second one. Things get more complicated because you can have different quality of chords (minor, major, dominant...) but you get the idea.
