Which of these symbols represent durations that are shorter than a half note select all that apply

Answer 1

In music notation, symbols that represent durations shorter than a half note include:

1. Quarter Note - represented as a filled-in note head with a stem.
2. Eighth Note - represented as a filled-in note head with a stem and a single flag or beam.
3. Sixteenth Note - represented as a filled-in note head with a stem and two flags or beams.
4. Dotted Notes (like a dotted quarter note) - which modify the duration of a quarter note (or other notes) but are still shorter than a half note by themselves.
5. Triplet Notes - which can also represent durations shorter than a half note depending on how they are notated.

Specifically, the quarter note, eighth note, and sixteenth note are standard notes that are definitively shorter than a half note.
