@ToddWilcox it provides following definition: "Pulse" - The Pulse is the constant beat underlying the music. It is steady and consistent. The pulse is assigned a note value so that it becomes a quarter note beat, or a... . "Beat" - this term has several but related uses. It's often another word for pulse, but can also refer to one instance of it (that is, one pulsation)

@ToddWilcox oooh, I always thought that accent is strictly tied to the pulse and I have somehow "translate" it to the rhythm, because my book always state that "beats" have accents.

Oh ok that's interesting. Based on your definition I thought it's "If the Beat is 4/X than emphasize the first Note of Beat1 and Beat3 per Measure." But with 2/4 I only have two beats with S w, so I thought it can only be the first note emphasized of beat 1 and since beat2 isn't emphasized at all then also not note 1 from beat 2

I think your answers somehow helped me, but your comment confused me a little. In my handwritten image the buttom should be the pulse consisting of two beats per measure and the top is the rhythm build on top of that pulse. If you tell me that my rhythm should actually be S w s w that somehow contradicts your original answere. For the rhythm accent S w s w I would need a beat of 4/8.

@ToddWilcox I know that there are multiple ways, in a two-four >beat< it's S w| S w, in a three-four it's S w w| S w w and in a four four it's S w s w| S w s w, but all those examples are for the pulse (the underlying, steady throb that can be felt in music, "beat" sometimes refer to one instance of it). Now we can build >rhythm< above the pulse (that's what sheets show) and if we state we have a 3/4 >pulse< and now build a rhythm with 1/8 notes on top of that I wanted to know how the defined accent from >beat< goes over to the >Rhythm< that's actually played.

@ToddWilcox based on It'sHedley's anwere your edit confused me more. I thought that if stated "accent on 1. Beat. per measure" in 2-4 it's Beat1 so Q q and then Beat2 so q q. You wrote the quaver >rhythm< as if it was a 4-4 >pulse<.

@Tim (at)Tetsujin I think I've got it, I've added an second example in my question that might make it more clear :-)

Would the last image I added be therefore correct?

I thought there must be some degree of logic behind the framework of musical notation, how would I know that it's mostly the first note per beat per measure that's accented if it's just statet that Beat1 is accented? Then somebody had to tell me that the trait of Beat1 just goes over to the first element.

that's mostly true but in theoretical interpretations and logic it's natural that if a parent element have a specific trait (here Beat1), then it's children elements have it also (here the 2 Quavers).

Yes, that artificial "a" is just an supportive element to evenly put 2 Quavers in one "Tock", so one in [Tock1; Tock1.5[ and the other in [Tock1.5; Tock2[. But when those 2 Quavers belong to Tock1 then I don't understand why the accent ("..") isn't an inherited trait for both: "Tick"("Quaver", Quaver) and not Tick"("Quaver", "Quaver") how I thought..

that might be true but doesn't provide me the idea you want to make clear.
