Final answer:
The first question to ask when deciding whether to modify pitch is what the desired outcome is. This will determine if pitch modification is necessary or not.
Step-by-step explanation:
When deciding whether to modify pitch, the first question to ask is: What is the desired outcome? This will help determine if pitch modification is necessary or not. If the desired outcome is to change the frequency or tone of a sound, then pitch modification may be needed.
For example, if you want to change the pitch of a musical instrument, you can modify it by adjusting the length, tension, or thickness of the vibrating element. This will alter the frequency of the sound waves produced, resulting in a change in pitch.
On the other hand, if the desired outcome does not involve changing the frequency or tone, then it may not be necessary to modify pitch. For instance, if you are simply amplifying the sound without altering its characteristics, increasing the volume will not change the pitch.
