Vani, I took the liberty of checking it out myself.
The answer (found from wikipedia):
An ostinati IS a motif.
An ostinato is always a succession of equal sounds, wherein each note always has the same weight or stress. The repeating idea may be a rhythmic pattern, part of a tune, or a complete melody in itself.A classical music example:
The basso continuo part from Pachelbel's Canon in D.
Riffs are ostinato's. Think "Iron Man" by Black Sabbath: (<-- click for link to youtube)
This chord progression is repeated over and over again.
Thahnks por reading!
-Seewah.
Well, technically this isn't a chord progression.
ReplyDeleteIt would be a chord progression if played on the guitar (unless individual notes are played).
But it's written with only a single melody.
Remember that chords are special kinds of triads! :D
LOL.
I lost some sleep because I didn't mention this...
