According to the information it can be inferred that Kristina had to sing during the Baroque Era with her own voice without the help of an electronic device such as a microphone because at that time it did not exist.
<h3>What is a microphone?</h3>
A microphone is an input device used to transform sound waves into electrical energy and vice versa in sound recording and playback processes. This device was created at the end of the XIX century.
Based on the above, it can be concluded that Kristina could not use a microphone during the baroque era to amplify her voice because the baroque was during the 17th century and the microphone was developed in the 19th century.
