Please choose the correct ending to complete the given sentence: Computers and Electronics: [header] How to sing into a microphone [title] Practice with objects similar to a microphone. [step] Even if you don't always have access to a microphone during your solo practice time, you will still get the feel for singing with an object in your hand. [substeps] You can use something like a hairbrush or water bottle to simulate the feeling of holding the microphone while you are singing.

Ending1: Alternatively, you can also use a foot pedal to achieve control of the volume of your voice when singing. Whatever your solo practice needs to be, you will be able to control the volume by this method. Ending2: Microphones are fairly heavy, so use an object with some weight. For example, if you are using a water bottle for practice, use a full water bottle rather than an empty one. Ending3: Write down notes as you sing into the microphone so that you can record them later on. Try to focus on words that are not too harsh. Ending4: You can also use small, flexible objects to simulate your voice. Use napkins, towels, or other objects to cover your hands so that the object you are using is hidden from view of the audience.
