Play/Sing in different spaces inside/outside of your home.
Then describe how the spaces change the timbre of the performance, being sure to include any observations you made or conclusions you reached.

I sang and played my instrument in both spaces, hope my answer works, although it's a little iffy

Explanation:

When playing/singing inside, whether it be at school or at home, there is more of a feeling of comfort because you know who is in the area and depending who is around can control the comfort level. Though when playing/singing outside it's obvious that sounds are going to travel much further, so with knowing that you don't fully have a sense of who is hearing what you're playing/sining, which personally made me feel very uncomfortable. Comfort levels are very important, because if are to be more comfortable it makes it so much easier to focus and enjoy the music. Another thing, when you/sing in a enclosed space like a room, restroom, or practice room, you are able to hear yourself, and the sound will be louder. When hearing yourself it can be both good and bad, depending on your confidence/comfort, and good being that you can hear and adjust. Although you could still do that outside. Also when playing outside weather is something, both for singing at playing. When it's hot my instrument gets out of tune very quickly, and singing while it's hot is very physically uncomfortable, and overall same thing when it is cold with slightly different results. There are personally more perks to being indoors when playing/singing compared to being outside, with comfort both physically and mentally, being more self aware, and just having more control with the environment.

your answer would be d.)
