I'd use only 'to'.
Student or Learner
Is it correct to say 'She was taking a shower on my music' (meaning that she was listening to my music)?
I'd use only 'to'.
Would both options be correct : to the sound of the music/to the beat of the music or on the sound of the music/on the beat of the music?
We generally do something "to" music.
She is dancing to rap music.
She is dancing to the music.
She is clapping to the beat of the music.
You can use "on the beat" but it's more of a musical term to show that someone is doing something on the main beat ie in time to the strongest beat of the music.
- You are clapping off beat.
- Am I?
- Yes, I need you to clap on the first beat of each bar.
- Was I not doing that?
- No, you were clapping on the half beat. That won't work! It proves you're good at syncopation but that's not what I asked you to do.
I don't know if you are musical at all but if you listen to a piece of music, you can count along with the beats. The most common time for music is 4/4 (pronounced four four). That means that you can count "1, 2, 3, 4" in time with the music. Sometimes you can only count to 3, it depends on the rhythm of the music. If you add the half beats, you count "1 and 2 and 3 and 4 and". Someone clapping on the beat would clap at the same time as they say "1, 2, 3, 4". Clapping on the half-beat would be clapping each time you say "and" instead.
Would it be also acceptable to say 'on the sound of the music'?
She is dancing to music.
She is dancing to the beat of the music.
She is dancing to the sound of the music.
I really can't think of a way to use "on" in the way you seem to want to, apart from "on the beat" and that has a different meaning to the one you started with.
She was taking a shower to my music.
She was taking a shower to the sound of my music.
I agree with 5jj, though. People don't generally take a shower "to music". That means that everything they do in the shower is somehow connected to the music, perhaps done in time, on the beat, in rhythm. That would be rather unusual.
She was taking a shower while listening to my music.
OK, got it!
But regarding music (in general) we say 'in rhythm of the music' or 'on rhythm of the music'?
Also regarding 'on the beat of the music' would both options be correct then: Mark's clapping on/to the beat of the music.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
Thank you for replying!
