new timing when

I would also add something, musically, a 6/8 should always be composed by two dotted quarter note, making [3-3], you say here it can be [2-2-2] (you also said [3-3-3] which looks like a typo) https://i.imgur.com/uJRHaj7.png
Ah right, we didn't actually consider mixed meters very much and I assumed it would fall into the complex-category and doesn't need to be timed like that, but we (read: dsco) found a ton of loopholes with that right now. The two options to avoid all of those are either 1) requiring them to be timed this way, which I find annoying for cases like this too, or 2) adding the following sentences at adequate places in the guide:Xenok wrote:
Yeah, so on osu, we should also alternate between 2/4 100 bpm and 3/4 150 bpm? Don't look kinda annyoing sv wise?
Xenok is correct that the time signature isn't determined by how the beats break down in a certain measure. The score he linked to is very indicative of many 6/8 songs so it shouldn't be looked at as an exception. It is much less common for music to switch time signatures every measure actually. It's *usually* pretty obvious whether something is 6/8 or 3/4 based on the emphasis patterns/style of the music if you have the ear for it.Xenok wrote:
I would also add it's "musically wrong" to say that America is mixed between 6/8 and 3/4. Actually, the song is only composed in 6/8 but composed with notes that sometime could tend to look like 3/4. We can see this in this music sheet for example: https://s3.amazonaws.com/static.musesco ... core_0.png
But well I think it's not a problem in the post to show the difference between 6/8 and 3/4 since it sound like a 3/4, but I think it's a good think to make things more precise!
Sorry for being annoying...
You're about half right. Time signature as a whole along with tempo marking (i.e., BPM) typically is what determines how many metronome hits are in a measure. 6/8 is almost exclusively counted in 2 and then further subdivided as triplets (i.e., tri-ple-let tri-ple-let) even in measures consisting of 3 quarter notes. 3/4 on the other hand is either counted in 3 or in 1 depending on the tempo marking (i.e. waltz is in 1 typically). There are a variety of ways that the tempo marking could be formatted to include this information (i.e., the tempo marking might be "fast waltz").Kagetsu wrote:
the proposal doesn't take care of the main thing it should be addressing, the metronome hits. a lot of those would be left omitted with this proposal (the whole purpose of the upper number is to denote how many times the metronome hits within a certain measure, as far as my understanding goes, please correct me if i'm wrong)
i gotta disagree with this, first of all why do "traditional" metronomes matter at this point? i mean we're in 2018 and i'm pretty sure electronic metronomes exist and are capable of representing compound or even complex time signatures.Bonsai wrote:
A "traditional" metronome only makes one type of tick-sound which represents one beat, and doesn't really have anything to do with the time signature that you want to play in that tempo -
yes, but you gotta realize the reason why representing the subdivisions with the metronome on simple time signatures (such as 3/4 or 4/4) isn't necessary: the beat on those is always a quarter note, so the notes always get grouped the same way, whereas for x/8 signatures, the way of grouping may be completely different from one song to another, you can have beats that last a dotted quarter note, for other cases it may be 2 eighth notes, there even exist 3/8 which uses eighth notes as the main beat. hence why electronic metronomes do mark the subdivisions for those time signatures.Bonsai wrote:
When a metronome is set to 60 BPM it makes one tick per second, if you're playing 3/4 in that tempo you take three ticks and mentally sub-divide each tick into two, if you're playing 6/8 in that tempo you take two ticks and sub-divide each into three ticks - Both signatures have the same amount of eighth- or quater-notes, but those notes don't have the same length, only the beats, and that's all what a metronome cares about.
this point was already explained, it just happen to be like that because osu uses simple time signatures only, which take quarter notes as the main beat, so i believe subdivisions doesn't have to be there to the metronome be aligned with the musicBonsai wrote:
That's what the metronome in osu! does too, if you set the BPM to 60 you have one white tick per second and will hear one tick-sound per second in the timing-tab, only when you hold ctrl it will further divide that into two or three ticks depending on what the BeatSnapDivisor is set to.
so uh i don't understand why you say that, i mean if it was like that why would we even bother to ask developers to add complex time signatures into the editor?Bonsai wrote:
A single metronome can't properly indicate irregular time signatures, because irregular time signatures aren't limited to one tempo.
this wouldn't be a problem if we were with the doubling equivalency method as there would be always a subdivision hitting the beats no matter whatBonsai wrote:
So this should make clear why using multiple BPM-sections is theoretically the musically most accurate method of timing irregular signatures in osu!. But since that's a relatively high effort, we only enforce the "simplified" version of sticking to one of those tempi, which is then consistent even if the song changes signature.
actually doubling the bpm and making all the notes half of the duration is just an equivalency, it would be still readable if you were to read a music sheet (although it would be more complicated because there wouldn't be an indication as to where the notes should be emphasized or how they are grouped), but it's none of osu's business honestly, if it was for this, the equivalence for almost all 1/3 based songs would be also labeled as incorrect as you would be converting a compound time signature into a simple one mapped with tuplets.Bonsai wrote:
Now one of the reasons for not deeming double-BPM valid is obviously that it completely incorrect musically, since it uses neither of the tempi that a song actually has, and messes up the meaning of both note-value and beat-value
i'd say it's the complete opposite of what you're stating, as for example this map's listing says it's only 72 to 108 bpm but the tapping speed required to play it is actually a lot higher than thatBonsai wrote:
1) it also loses any indication of gameplay, as it doesn't even say how fast the actual "tapping-speed" of the song would be
well that's something that can be addressed with some rulings too, i don't think it would that difficult to so, also the method you're mentioning of halving/doubling because of time signature changes had happened a lot of times, refer to maps like this or this where you could theoretically change the time signature instead of changing tempo.Bonsai wrote:
2) it would make songs that switch between signatures be timed even more inconsistently, as you'd have 100 BPM for one part, then 200 BPM for another and then again 100 BPM, which messes up the SV along the way too. On average, the effort for using doubled BPM would be lower (though it could be higher in some cases too), but at the cost of not only losing any musical significance, but also losing an< significance for osu!. It wouldn't represent tempo in a consistent way, and wouldn't give the player any indication of what they can expect from the song. Basically, BPM would be completely meaningless because it would have a different meaning for different songs (or even for the same song when a signature isn't clearly identifyable), so at that point it wouldn't make much sense to have any timing-regulations in the first place.
i don't even know what to say, if you think the metronome isn't important at all then i don't know why we are discussing this proposal in the first place. why not set any time signature if the metronome isn't important at all?Bonsai wrote:
1 2 3 4 5german counting:
Who says that the metronome-concept you're describing is relevant in the first place? The osu!metronome™ never really helps anyone with maintaining a certain pace at all, because you can't hear it in the editor (except the timing-tab where you usually don't spend much time in) and you can't hear it during gameplay (except for Nightcore-mod, which sounds terrible with doubleBPM in almost every case). The field where you put in the value that you are proposing to double is literally titled BPM for "Beats per Minute", if you double that value it's not the correct BPM anymore. I don't see how these characteristics that you are demanding of a metronome are relevant for osu! at all.
doesn't change the fact that they would still mark the subdivisions which is the point i'm trying to convince you about thoughBonsai wrote:
(4: A metronome that marks beats with stronger sounds and subdivisions with weaker sounds does depend on the song, and the osu!metronome™ is one of those. Also, you can just write irregular time signatures as "additive signatures", in which case they are not written as 7/8 but as (2+2+3)/8, which is just a stylistic difference. Thus, 2+2+3 and 3+2+2 would be different signatures, and hence require different metronomes)
so uh i think i already addressed most of the points you're stating now.dsco wrote:
@1: you seem to have some misconception that not doubling the bpm results in a less-accurate tempo to what the music would be played as. for starters, this is an incredibly subjective thing, as some people will alternate 1/2 divisor at bpms even as low as 180 and above while single tapping 180 below, and some will single tap 1/2 divisor all the way to 280.
secondly, doubling the bpm is incredibly inaccurate in many cases too. take these three songs: [1] [2] [3] [4]. are these songs 384bpm, 580bpm, 320bpm, and 345bpm? or are they 192, 140, 160, and 115bpm?
i'm fully aware of this and it's why i agree with the proposal for regular time signatures, actually this is the fourth time i mention it. i have yet to see an example of what a metronome would sound like on irregular times signatures thoughdsco wrote:
metronomes do not always play to the lowest subdivision of the time signature anyways. take 12/8 or 6/8 metronomes for example, in compound meter. it is extremely common to practice these to 4/4 or 2/4 metronomes respectively, especially at higher bpms. in fact, when taught, they are essentially always taught as triplets in 4/4 and 2/4, because the eighth notes are more easily and comfortably played as triplets than individual beats.
yes, the whole discussion is kinda pointless anyway because the metronome would only show on the main menu screen and when using nightcore mod, right?dsco wrote:
just because there is a metronome that plays when you insert a bpm in osu doesn't make the bpm revolve entirely around the rate at which the metronome ticks (which can be changed simply by holding ctrl in the timing panel anyways).
