I had a discussion with a friend today about how a certain part of a song is supposed to be played. Over time, several more people came in and added their own opinions and explanations, and now there is total confusion. Unfortunately I wasn't able to find the right keywords to google this problem, so I'm asking here. (English is not my native language, so I'm not sure if I know all the music-related words - feel free to edit of course.)
There are pieces of the song where notes which are written as actual triplets occur at the same time as 3/16+1/16 notes, such as the areas marked using rectangles in the following picture (ignore the upwards arrows, they were manually added by my friend):
Now, my interpretation is that:
- The parts I marked with horizontal bars are affected by the "swing rule" and played as 2/12+1/12 instead of 3/16+1/16.
- The measures in the rectangles are played liked this (excuse the crude sketch and misaligned notes):
- The notes I circled are played at exactly the same time.
For reference, this is the original soundtrack from which this song originates - I already skipped to the relevant part, starting with the first measure in the second picture I posted (at 0:37):
The same as orchestral version (at 0:35):
Now the following questions came up:
- Does this "swing rule" apply to 3/16 rests + 1/16 notes as well as 3/16 notes + 1/16 notes, even though only the latter is shown in the example notation next to the tempo? (I thought yes)
- What is the real, correct name of this "swing rule" (so we can Google it)?
- Is it true that the circled notes in bass and treble are supposed to be played at exactly the same time, so there is no polyrhythm (when looking only at the notes sheet)? (I thought yes)
- Are they actually played at the same time in the original soundtrack? (For me it sounds so, given that the bass instrument has a softer "fade-in" of each note - somebody else said there is a slight delay)
- Does the actual physical position of the notes on the sheet matter? Somebody said that there is a slight delay in the original soundtrack (something like 1/32-1/64 which I didn't really hear) and it is also visible in the notes sheet because the 1/16 note is slightly shifted to the right relative to the third triplet note.
- Is the duration of the three notes inside a triplet of equal length? (I thought yes - 2/3 the length of the non-triplet version of the same note)
