According to the information it can be inferred that Kristina had to sing during the BaroqueEra with her own voice without the help of an electronicdevice such as a microphone because at that time it did not exist.
<h3>What is a microphone?</h3>
A microphone is an inputdevice used to transform soundwaves into electricalenergy 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 17thcentury and the microphone was developed in the 19th century.
