Okay, I just learned that the Casio vocal synth keyboard comes with animal sounds. Granted the default vocal tone sounds like IA's old Cevio english, not the AI so it have more noise than a dot matrix printer. But it have a nice retro vibe, like something Daft Punk would have made. And the whole thing do not have that anime weebo aesthetic, purely for professionals.
Slur: Arc-looking mark over one/more notes on music notation. Means to slide from one note to the next, like a pitch bend.
Tie: Looks like a slur, but means to combine the notes together into one longer note. You can tell these from a slur because the tied notes will be of the same pitch. (Slurring between notes of the same pitch wouldn't make any sense.) This mark only exists because notated music is divided into measures, and a means of putting long notes over measure lines was needed.
Pp, p, m, fortissimo/ff: Tell how loudly to play a piece.
