There may be 5 Tips for Playing Song Live, Let's see

1. Practice, Practice, Practice. This one really got to go and without saying, but it would be just so much importance that it is and will be one I leave it out. Before you set foot on stage, practicing the song until you can play and sing any one of them from memory. Yes, it was a lot of hard work through exercise routine, but it will surely be defeated and tiring, forgetting the words or should be stopped and started with a balance of multiple steps into a single and a song. So that the audience can know that you are ready, and they will feel more attention to the music you if they think you know what you are doing it big. There is no such thing as too much practice that should be done.
     
2. Take a backup and replacement. Try to have a replacement on hand for anything that might be lost or destroyed it during the set for you. As in the old adage says, of course, better to be safe than sorry. It means carrying a lot of extra guitar picks, a capo or a slide ... even a spare backup guitar or amp, if you have one. It certainly would be a shame if your killer set was cut short due to broken strings or tubes burst.
   
3. Stay hydrated. And with "Stay hydrated," I mean drinking a lot of water, not beer or soda. Singing is hard work, especially of you play an instrument well, and you will probably end up a sweat and get thirsty. Keep a water bottle nearby to breathe, because you will need it. Singing has a tendency to dry out your throat after a while. Keep your vocal cords with water before and during a show, and of course they will always take care of you.
   
4. Do not talk too much. Many young musicians seem to have a problem with not knowing when to stop talking to the audience. I'm not saying that you do not have to interact with the audience at all, I was just saying that it's not a good idea to spend 7 minutes between songs, explaining where you write each one and what all the lyrics around. More often than not, your time on stage will be limited, so try to fill that time with the music as much as possible, because that's what the audience interested. Your songs is what they will remember you and keep coming back to see you to, not the ability to speak in public.
   
5. Throw some famous blanket into a mixture called a simple but classy. Even if you are able and have enough pure and original material to fill all the slots of your grace period, plays classical audience can sing along is a good idea from time to time. This is a great way to engage your audience and get them involved in your performance, and also show them that you can do more than just the original (not that there's anything wrong with doing all originals, of course). It is also an opportunity to show the audience some of your musical influences.
