Not quite! But it's even easier to do! Here's what you'll need:
It may? help some people, but the title should have been:
Mi So Re Do? (but the 15 char limit stopped that)
Also:
The image was only broken up because the screen wasn't big enough to take screenshots.
Hints:
5 go like this: words -> music -> hidden word
2 go like this: words -> slightly hidden message
1 goes like this and should be the lead-in: words -> message (not really hidden)
All the text is important
2 of the clues are about HOW to get the final answer
6 of the clues are WHAT you need to get the final answer
Yes, a thick creamy dressing is relevant
What next? There are two linked clues in the music, the rest can be interpreted by itself then put into the music after
You might want to analyse the 'comments' for alternative meanings.
'More...*between the accents' could be 'More...* between the accents' for clarity
On TSL @humn picked up on So "far" - BAD having B-A-D. This clue has 3 parts, of which BAD is one of them. (There is also a subtler hint)
In that clue (^), two parts are how to decipher the music and one part tells you what in the music you need to decipher.
@Volatility was correct in finding 'mayo': you need to find similar items

The subtler hint is in the wording 'so far'
- is a tenuto [which is basically a hyphen on a note, like the first note in the left hand (bottom line) in the 6th bar.
Warning! One step of the solution!
Take the tenutos in the music. They give ADCABBAGE, but 'so far' we need to use solfa (i.e. before the message) so the first A gets turned into a re. This gives a message - REDCABBAGE or red cabbage.
Sections are important - but what information goes with the letters that you are given?
So... yes, the bar numbers are linked to the sections. Why don't you try applying some knowledge here (or ask google)?
What can you do with {(O,11);(C,12);(H,22)}?
The last part needs a bit of musical knowledge.
@humn was semi-right when they said they had found the last ingredient - something used there is correct.
What elements of the music have you not yet used?
Alright, I'll say it - it is morse code...
Unnecessary, but here is the sound file (on Dropbox).
And here is a PDF, but across two pages, and 'Made with MixIn' is at the bottom of both pages (also Dropbox).
Perhaps a smidgen of knowledge will be needed, but not too much.
Everything is clued in some way, so no need to do something radical.
For reference, I use a movable do
