Solved Notes mixing together

Just to start off, I am still new to java so this might be a dumb error with the time.

I wanted to create a simple plugin that plays a specific song when you use a specific command, but the notes just kinda mix together and play at once.

This is the way i play the notes

Code:

Bukkit.getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
                @Override
                public void run() {
                    p.playNote(l, Instrument.PIANO, Note.flat(1, Tone.E));
                }
            }, s1);
            Bukkit.getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
                @Override
                public void run() {
                    p.playNote(l, Instrument.PIANO, Note.flat(1, Tone.E));
                }
            }, s1);

The "s" variables are of course "long" and "p" is the player.

Am i supposed to stopSound after every note? And if so, how exactly, because the BLOCK_NOTE_BLOCK_PIANO doesnt seem to exist?

 

Oh so that's how
scheduleSyncDelayedTask works. Thanks for just giving me a small hint on my otherwise dumb question
