You are unnecessarily mudding the waters here. And you are stating a lot of bullshit. Yes, you can notate alterations when they occur, instead of using a key signature, but if you always have Bb, Eb and Ab, why would you notate them when they occur, instead of using a key signature? Music notation is a convention and was created to allow musicians to "remember" and be able to reproduce a piece of music, instead of having to memorize it. Making things easier is not ********, it is a clever thing to do.anomandaris1 wrote: Fri Oct 26, 2018 9:15 am Melody can start on any note... Key, tonality,scale topics can get confusing, because of how much Western notation and theory is based on the diatonic scale and meantone temperament. I find the sharp vs flats debates ******** unless they actually are supposed to mean anything meaningful- unequal systems like just intonation and similar. Still, atonal integer notation is superior for any edo.
And tonal melodies don't start in "any note". They usually start with a note of the tonic chord (for example, in C Major they will most likely start with a C, a G or a E). If the melody starts in anacrusis, you may have a short cell starting with other notes, but that cell will land in a note of the chord in the strong beat of the bar.
Theoretically you may, but it would be really stupid using the key of A# when you have Bb, wouldnt you agree? And a twelve note melody isn't what we are talking about here (I don't even know what is a twelve note melody... I know what is a twelve note "series").anomandaris1 wrote: Fri Oct 26, 2018 9:15 am In general, you may use any piano key, if you know what are you doing (JW had some nice 12note melody in one of the Harry Potter movies).
WTF are you talking about? Medieval/renaissance melodies aren't tonal melodies.They may lead to some confusion in people who are not familiar with modes, but those that know modes (not the "jazz modes", which are no modes at all, but the real ones that were used in medieval and renaissance music, the so called "church modes"), know exactly what is the universe they are based on. That has nothing to do with modern key signatures.anomandaris1 wrote: Fri Oct 26, 2018 9:15 am Check which notes feel the most stable, are most repeated or with longest duration to determine the tonic. It may change from phrase to phrase - there are many such melodies (especially in older medieval/renaissance music; or even pop/rock).
"Check which notes feel the most stable, are most repeated or with longest duration to determine the tonic."??? Really? What if the melody has a repeated G, but then descends into C? Would you say the the G is the tonic? And that the melody then has a second tonic? WTF is that advice you are giving?
Regarding the modern atonal music, like the second Vienna school, or the music of Satie, Ravel, Debussy, Bartok, etc., when they don't use key signatures that's because the music doesn't follow a key (any key), therefore, a key signature could lead the musician to an erroneous impression, while it would still be meaningless and, most of all, useless, because many alterations would be still occurring outside of the key signature, and would have to be notated when occurring.
