How the Allay should interact with instruments and tones

The other day I was testing Allay in the new Beta and I thought it is a great addition to Minecraft that has a lot of potential, it's for this that I think my suggestion could make the player's experience with Allay more diverse, complex and rewarding.

There are 16 instruments and 25 pitches that change the sound and I think that this existing feature could be used to further expand the uses of the Allay.

The Allay should pick up specific items, item groups or item variants at different distances depending on the instrument and pitch. The instrument blocks that I propose are the emerald, gold and iron blocks.

Example 1. If you give Allay a Protection IV enchanted book then Allay will collect only that specific item but if you place an emerald block then Allay will collect all enchanted books in the game and if you place a gold block then he Allay will pick up all Protection enchanted books and if you place an iron block then Allay will pick up all level IV enchanted books.

Example 2. If you give Allay a spruce planks slab then it will only pick up that specific item but if you place an emerald block then Allay will pick up all the slabs in the game and if you place a gold block then it will Allay will collect all slabs from all types of wood.

Now depending on the pitch of the note block the pickup radius of the Allay will be shorter or longer.

For each tone the Allay's pickup radius is increased by 4, giving a total of up to 100 radio blocks with the 25 pitches.
