Question

1. a choral leader says, \i keep hearing someone who is off - pitch.\ what does this most likely mean?

someone is singing higher than required.
someone is singing louder than required.
someone is singing faster than required.
someone is singing softer than required.

Explanation:

In music, "off - pitch" refers to a note that is not at the correct musical pitch. Pitch is related to the frequency of a sound, which in singing terms can be thought of as how high or low a note is. Singing higher than required would mean the pitch is incorrect. Singing louder (amplitude), faster (tempo), or softer (amplitude again) are not related to pitch.

Answer:

Someone is singing higher than required.
