Article: If you feel your singing voice is awful, it is likely because you’re not using specific parts of your body correctly. When singing, stand or sit up straight. Keep your mouth slack, flexible, and loose, and exhale gently. Sing from your diaphragm to project. When you push your voice forcefully or strain it, your body will tighten up. This will, in turn, strain your throat muscles and you will lose much of your tone and air supply. If you're pushing your voice, it will sound out of tune or will crack and break. Several singers struggle with proper tune and pitch. One way to perfect your pitch and tune is to play notes on the piano and imitate them with your voice.  You can also use apps, like Vanido, to help perfect your pitch. If you’re really struggling with your voice, try this vocal fix. Watch your jaw move as you say “A-E-I-O-U”. Determine what vowels your jaw closes on. It is likely the vowels E and U. Try again, taking care to keep your jaw propped open. Practice singing while keeping your jaw equally open. This may take a lot of practice to perfect but will eventually become natural. Having your mouth open equally on all sounds will help keep a uniform and even voice. If you’re struggling to keep your jaw wide, wedge your fingers or a piece of cork in your mouth and try again. Practice until you no longer need the wedge to keep your mouth open. Vibrato is the way to change pitch in your voice. It allows your singing to be breathy and charismatic. Knowing how to control your vibrato is a good thing, as some contemporary singers, like Ariana, have a small amount of vibrato so having the control is important.  Your vibrato may sound messy or feel loose and sloppy in your throat at first. Don't worry -- just keep practicing and it will become more natural and sound better over time. When you're working on your vibrato, imagine your voice spinning out of your mouth like a laser. Practice vibrato techniques. For example, stand in front of a mirror. Press on your chest with your hands then raise your chest up. Breathe in and exhale, while holding your chest steady. Sing a note and hold it as long as possible without moving your chest. Halfway through, press down with your hands but keep your chest raised to meet the pressure. Relax the back of your neck and keep your jaw open wide as you belt out the note. Imagine the air in your mouth swirling while tucking your chin slightly and keeping your chest raised.

INPUT ARTICLE: Article: Sweep a dry dust mop across the surface of the floor every few days to remove everyday dirt.  Even though laminate flooring is fairly scratch-resistant, excess dirt, hair, and debris can cause scratches to develop if allowed to build up over time. Regular sweeping prevents such scratches from forming. Instead of using a dry dust mop, you could also use a vacuum with a soft brush attachment. Do not use a standard floor brush. The stiff, straw-like bristles on the brush could damage the surface. Sweep in the direction that the laminate floor tiles were laid. Doing so allows you to pick up any debris that falls in between the grooves of the laminate flooring pieces.

SUMMARY: Regularly sweep the floor.
