Dynamics usually refers to the volume of a sound or note.
DYNAMIC MARKINGS tell you how loud or quietly to play.
To get a variety of different volumes you can use these symbols:
ARTICULATION
Articulation tells us how much to separate the notes.
In theory all the notes of a bar add up to one continuous sound, but actually there are tiny gaps between them.
If you exaggerate the gaps, notes are short with plenty of space between them, and you get a staccato effect.
Staccato is marked with a dot above or below the notehead.
If you smooth the gaps out there is not breaks between notes and you get a slur.
A slur is marked with a curved line joining some notes.
