Question

On which musical properties do tonic and agogic accents demand emphasis, respectively?

volume and pitch
duration and pitch
pitch and duration
volume and duration

Answer 1

Agogic Accents stress which is perceived solely because of prolongation of duration, not due to increased volume or pitch variation

so I'll say duration and pitch

Answer 2

The answer is

PITCH and DURATION

Step-by-step explanation:

An accent in music is an emphasis, stress or stronger emphasis placed on a particular note, set of notes, or chord, and it can be indicated by an accent mark.

A tonic accent refers to an emphasis on notes caused by a higher pitch.

An agogic accent refers to an emphasis placed on a note through prolongation of duration.
