Yes.
Although it is the relative minor, it still uses different notes in the scale (eg - G# in A minor)
That's why Bach wrote 48 Preludes and Fugues - one for each key.
(I know on the piano C minor and B# minor are the same, but that wasn't the point)
Is changing from a major scale to the relative minor (C major to A minor) technically considered a key change?
Yes, it is. Whenever the tonal center is changed to a new note, you have a key change. Even though the key signature does not change, there are significant differences between C major and A minor. First of all, there should be G sharps in the true key of A minor (this provides the leading tone). Each key has its own leading tone, but in minor keys, we have to add them in the form of accidentals. Some composition and theory experts consider the use of relative minor without the appropriate leading tone to be modal, and not in the true key of the minor.

Yup, sure is.
In most sonata movements in which the first theme is in a minor key, the second theme is in the relative major.
However, in most sonatas in which the first theme is in a major key, the second theme is in the dominant major (oen more sharp or on fewer flat).
I don't know why the composer seldom writes the second theme in the relative minor, but I suppose he could.
It is ABSOLUTELY a key change! %26quot;A%26quot; minor has a new tonal center and other relationships in many ways similar to C major, but absolutely different in tonic-dominant relationship to C major. It is part of western music's evolution which has made classical music so amazing and powerful.....even a core element of modern music, from heavy metal to hip hop, folk, jazz, alternative, etc.
Yes. A key change is defined by a change in tonic/tonal center, NOT just whether or not the notated key signature looks different.
yea i guess...heck i thought key changes would occur if a piece changes key by itself...
Yes.
