It's the end of March. It may be time to take down my ornaments. 
 
My neighbors have articulated their feelings to me. 

Yeah, articulation is reserved for the attack and release of a note (accent, staccato, legato, marcato etc.).  Ornaments are added notes like trills, grace notes, and quick runs and are usually notated with a symbol (or improvised in many cases).   There are other special techniques that do not fall under either category such as muting or bowing alterations.

I've missed Pedro's articulations.
 
Or are they ornaments?

I'm just waiting for the thread about accidentals.  That's apparently my best musical talent. 

Craigb, BayouBill already started that thread.
 

Not sure, but I once wrote an abomination.

Yeah, abdomen songs are the breast.

Good answer, thanks. And pretty much what I'd guessed. So hammer-ons and pull-offs would be articulations, since they don't add notes but instead refer to how the note is generated. I'm guessing slides fall into that category, too. But not mutes? What is the musical notation for a mute?

What is the musical notation for a mute?

I'm used to seeing something like "P.M. ...................................." under the staff (for palm muting).
 
Now you've got me wondering what a pinch-harmonic falls under since you kinda need both parts (a different type of attack and an additional note).

Hi,
 
Sorry ... didn't think this was a detail on a synthesizer or the like. I thought it was a more generic music question!

E rotated right, looks similar to the letter M
 
Since you do play piano, next question you (or anyone else who happens to stumble on this topic) might want to ask is, what's the musical notation for 'Piano Pedals'? Sustain Pedal marker is a 'Shallow curve between note/chord' to mark start and end points. Not to be confused with the Slur marker (legato)!   Damper Pedal, Ped is on/start, and * (asterisk) marker means damper off/end.
