In one sentence, describe what the following article is about: Before you start a big project like putting a music group together, you need a clear goal and vision. Determine what kind of group you want so that your vision for the group is clear from the start. You will need to choose the style of music for your group. How many people you have in the group, where you look for singers and instrumentalists, and how you get an agent or manager will all depend on the musical style. Most of the popular styles for singing groups are madrigal, a capella, pop, hip-hop, vocal jazz, rock etc. Where you look for your new group members will depend on what kind of group you want to make. For example, if you want a religious singing group, you should look for members at church, or maybe people who sing in a church choir. If you want people who can play instruments, you might want to ask people who are in band class at your school. This will depend on a number of factors. Some styles of music will feature only 2 or 3 singers, whereas others such as pop or a capella can feature 5 or more. You will need to decide on the gender of your members. Do you want an all girl or all guy group? Or a mixed group? If you decide on a mixed gender group, you will also need to decide how many male voices and how many female voices you will need for the right sound. If you are a rock or country group, you might only have one singer. Everyone else in the band will need a role other than back up singer. In groups like this, often there is a lead singer and a group of musicians that play guitar, bass, and drums. To find people to join your group, you could organize some kind of audition so that people will come to you. You'll need to advertise the event (make fliers, tell everyone you know, put an ad in your local newspaper, etc.). Post fliers around your school, at local businesses, at your church, and at local events. Take out an ad in the newspaper. That can help interested musicians and singers find you. Talk to people at your church or community center. They can help you spread the word about your group and the audition. Try announcing the event on social media like Facebook and Twitter. You can also post an ad on Craigslist and other websites. If you know people who are already in bands or singing groups, ask them if they know anyone who is currently looking to join a group. Post about it on social media. Ask your old band or music teacher if they know anyone interested. Do whatever you can to draw attention to your project so that you can find the talented people you'll need to be in your group. Even if all of the singing members have equal parts in the group, there still needs to be a designated leader. This will be the person who interacts with your manager, booking agents, members of the community and press. This person will have to make sure the vision of the group remains intact. Make sure its someone who can work with all the personalities in the group. Remember, you all have to be able to get along and collaborate effectively. A group will function better if everyone is clear on what roles they are supposed to play. Typically, parts are assigned based on people's skill level and talent in specific areas. If one group member has a beautiful tenor voice, it would be silly to assign them the alto singing parts. One group member who is good at choreograph can be in charge of putting together dance routines. Certain group members might be better at playing a certain instrument or singing a certain style better than others. Assign roles based on everyone's individual strengths and expertise. In a rock group, it's probably going to be more likely that each person plays a different instrument and there is one lead singer. Make sure everyone understands they can't always be in the spotlight. For example, not every rock song has a drum solo so your drummer can't always be featured.
Summary: Decide what kind of group you want. Decide what kind of voices you want for the singers in your group. Hold auditions. Ask around your community. Identify a leader. Determine what parts each person will play.

Perhaps the best way to protect yourself against carbon monoxide poisoning is to purchase and install carbon monoxide detectors in your house. They sound an alarm if they detect carbon monoxide, so you can leave the house. Check the batteries in the spring and fall when you adjust the clocks. Anything that could potentially leak carbon monoxide should be serviced by a professional at least once a year. That includes gas stoves, gas water heaters, gas furnaces, and anything that burns coal or oil. Call your local gas company immediately if you smell natural gas or hear a hissing or roaring sound coming from a pipe. Cars release carbon monoxide, so you can get carbon monoxide poisoning if you let your car run in your garage. It can also leak carbon monoxide into your house. Turn off your car as soon as you enter your garage. If you are burning anything in an oven or fireplace, it should be properly vented to the outside. Always check to make sure the flue is open to let the smoke out. Similarly, don't use a gas-powered generator or grill inside the garage or house. If your heat is off, you may be tempted to try to heat the house by opening the door on your gas oven. However, that can leak dangerous amounts of carbon monoxide into your house, particularly if the fire goes out.

One-sentence summary -- Install carbon monoxide detectors. Call in the professionals. Turn off your car when you're in an enclosed space. Check for proper ventilation. Don't try to heat your house with a gas oven.

Problem: Article: The midnight mass commemorates the birth of Jesus. La Misa del Gallo means "The Rooster Mass" since it is believed the birth of Jesus was first announced by a rooster's crow. Listen to the boys' choir perform during the candlelit service. While the mass is held countrywide, the most impressive service is in Montserrat, 60 kilometres (37mi) outside of Barcelona. The main Christmas meal is usually eaten very late, just before the midnight mass. A common traditional Spanish entree is turkey stuffed with truffles, but coastal regions such as Galicia serve seafood as their main dish. Celebrate with a large dinner. Finish your meal with traditional desserts, like turrones (candy with almonds and honey), polvorones (almond and cinnamon shortbreads), and Roscon de Reyes (a fruitcake in the shape of a ring). A common saying on Christmas Eve is "esta noche es Nochebuena, y no es noche de dormir," which translates to "This is the Good Night, therefore it is not meant for sleep." Many families will sing and dance in the streets and party most of the night, or they will sing carols around the tree at home.
Summary:
Attend La Misa del Gallo if you're religious. Have a feast late in the evening. Sing carols and dance around the Christmas tree.
