Hi, I need to know how to make an item play a song with noteblock sounds, when you use it (Right click). I also need to know how to make it select a song from a GUI, opened by shift+right clicking with the item. Could anyone help me please?

Hi, I need to know how to make an item play a song with noteblock sounds, when you use it (Right click).

playing one note: BlockNote.java, method "onBlockEventReceived".  so something like

par1World.playSoundEffect((double)par2 + 0.5D, (double)par3 + 0.5D, (double)par4 + 0.5D, "note.harp", 3.0F, var7);

where par2-par4 you would use coordinates of a player (posX..posZ). when item is right-clicked method "onItemRightClick" is triggered, there will be probably part of your code. test for shift - "player.isSneaking()". the music playing would be probably handled in tick handler (of a server?), where it would remember how much ticks passed from start of a song and when it's next note's turn it would call playSoundEffect on a position of a saved player (!more players can play a song at the same time!).

I also need to know how to make it select a song from a GUI, opened by shift+right clicking with the item.

you'll need to learn how to create GUI and how to use custom packets to keep it in sync with server:

selected song would be probably saved in ItemStack or just in item damage.
