Suspension: A suspension occurs when a note from the previous chord is held over into the next chord before resolving downward. It creates tension and then resolves harmonically.
Appogiatura: An appogiatura is a type of embellishing note that leans on or emphasizes a dissonant note before resolving to a consonant note. It adds emotional intensity to the music.
Escape Tone: An escape tone is an embellishing note that resolves by skipping away from the preceding chord tone rather than moving stepwise. It creates melodic interest and adds color to the harmony.
