You would want to start by turning the trail and each note into a separate decal (image) which can be done here
You would then want to use a seperate particle emitter for the trail and each music icon/symbol, set their ‘Texture’ property to rbxassetid://DECALID which can be found in the link to the decal
This will require some scripting. I used this yellow trail and particles of Julis Cole as an example. You will have to change settings for the trail and particles emitters + add more particle emitters to your liking.
