This is a very clever and well thought out puzzle, and it was very smoothly assembled! The use of sound (having bass complementing having legs, no eyes vision sounds, the whole works) was very well done! I loved that each item was measured in worth by the sense lost or renewed in regards to perceiving the daughter.
The actual tune(s) were a bit repetitive, but due to the nature of always replacing parts, it wasn't overbearing. I think at least doubling the measure count might help alleviate this. I know another difficulty with this is that the tune changes must immediately be recognizeable and so variations in how much melody or other interplay involved would muddy this concept. All that being said, you did very well with the sound engineering to help encapsulate the entire experience.
Overall, incredible work!
