No I don't mean aeolian as fixed to a. a piece by Stravinsky that uses ionian and aeolian (and other modes) but certainly not major and minor.daniel-b wrote:Sorry, i don't see the difference until yet. Any example why a piece of music is in aeolian and NOT in natural minor?visa tapani wrote:It's not natural minor if it's not used in a functional way, just as ionian is not major if it's not used functionally. For example Stravisnky uses aeolian and ionian but rarely major and minor.daniel-b wrote:Why did you call it aeolian? It's only natural minor, nothing special...
Or did you mean is aeolian fixed to a?!
In western classical music natural minor tends to appear in an overall minor framework, with melodic and harmonic minor. In A minor, the fundamental chord progression of this framework is Am-E-Am (which follows the harmonic minor). However, if one was to play a descending scale starting from a, one would probably use the natural minor scale. If one was using an ascending scale starting from, say, e, one would probably use the melodic minor scale. Most harmonic progressions would utilize the harmonic minor, but the III chord (C major in Am) would almost always be according to the natural minor, ie without #7.
Not a good explanation, sorry. The most important difference is the underlying harmonic framework of Minor, which is absent in aeolian. Anyway, if one was to analyze the Stravinsky example as using minor and major one would be gravely mistaken.
