What if a piece changes key?
« on: July 13, 2017, 07:00:08 AM »
I have written an Étude that starts in B major and ends in C major, if I write it down, should it be Étude in B major or Étude in C major?

Just "Étude" will do IMO. Not even necessary to give it a number (e.g., "No. 1"), unless you're certain there will be a "No. 2".

Alright, but still, if a piece changes it's key, is it in the key it started in, or the key it ends in?

There's people here much more expert in this than me, but if it starts in a key, and then changes to another, well, it's exactly that, B major at the beginning and C major at the end (in your specific case). So it's neither one nor the other, nor both either.

The simplest things are complex and that is esp. true re: the key of a given work (though there's always exceptions, eg: popular songs are often straightforward).  The Wiki explanation is as good as anything I've seen:  https://en.wikipedia.org/wiki/Key_(music)

Ugh, yet another explanation of key as equivalent to scale.

Keys are not scales!  Keys are hierarchies of harmonic relationships, which do not have to rely on a scale.

Alright, but still, if a piece changes it's key, is it in the key it started in, or the key it ends in?

If it's always moving towards the ending key, then I'd say the whole could be judged as being in that key (eg the first song of Mahler's Lieder eines fahrenden Gesellen), but just modulating at some point isn't the same.  Best to avoid a key designation.  It's not really necessary anyway.

Agree, Mahlerian - it's the modern practice in any case.  I thought the Wiki explanation specifically warns against interpreting scale as key  : "Although many musicians confuse key with scale, a scale is an ordered set of notes typically used in a key, while the key is the center of gravity, established by particular chord progressions..."

True, and I think it's another indication of how tonality is just not the natural language for the average listener anymore.

I missed that, sorry.  I was reacting to the first sentence, really, and certainly not to you personally, so I hope you didn't take offense.

Eile macht Weile... ;D No offense taken, Mahlerian, I enjoy and am grateful for your posts!

Progressive Tonality is the term for that.  Karl Neilson, among others, is known for it.

"I can not think of a piece of this nature where the composer stated the key, if you think on it one sec, for obvious reasons, lol."

Naming a piece and stating the key is such a common practice bit of business, and embedded in the general consciousness, that causes, imo, any number of amateur and beginning composers to still think in that mode, for both the actual writing and title.  It is a mental reflex, maybe some think your piece sounds more 'official' or legitimate with that old tag on it, but we all know that just ain't so.

Progressive Harmony, shifting key centers without returning to 'home base,' can happen within a movement (your Etude) or within the key schematic of multiple movement works.

Stravinsky's Piano Sonata has no key name, and its three movements are in: 1 C / 2 Ab /3 beginning in and ending in E major.  The first movement C is in the center of its upper and lower major thirds, outlining an augmented triad.
 
Ditto Barber's piano concerto, with its schematic a sequence of descending minor thirds:
1st movement beginning and ending in  E minor,
2nd movement primarily in C# minor (the relative minor -- descending -- from E)
3rd movement "mostly" in Bb minor (polite use of the enharmonic for A#) that again a minor third lower than the second movement.

Call it "Etude," or if you will, Étude :-) It only needs a number if there are others; will get a number if others come later.

P.s. Nitpick, but its the literal truth:
"I've written an Etude.... If I write it down...."
Well, you haven't written anything until, ya know, it is written down [memory and midi or other recordings don't count as 'written' lol].


Best regards

Agreed, also for composers and musicians, of course.  Any and all of the older forms can be used, done, and their names used, and without stating a key.

Gustav Mahler wrote a Symphony No. 2 in C minor (ending in E-flat major), a Symphony No. 4 in G major (ending in E major), a Symphony No. 5 in C-sharp minor (ending in D major), and a Symphony No. 9 in D major (ending in D-flat major). And although he didn't give a key designation to the Symphony No. 7 I've seen it referred to "Symphony No. 7 in E minor/C major" which is.... dumb but whatever.

Also: Chopin's Fantasy in F minor (ends in A-flat major), Ballade in F major (ends in A minor), Scherzo in B-flat minor (ends in D-flat major). And Schubert's Unfinished Symphony in B minor technically ends in E major because he didn't bother to finish the remaining movements (which presumably would have been in B minor). I guess that kind of answers the OP's question.

So much for my limited thinking over the rep before firing something off from my typewriting keyboard!

Your very nice and concise list of pieces that are named as being in a key but are in a progressive tonality scheme that does not politely "go home" is rather perfect. 

This 'clearly' means that the answer to the OP's question is:  Name the key in your title -- or don't. :-)

Say it's in G-sharp minor, that'll really spice things up.
