I still haven't managed to learn how to sing and play in unison. As soon as I start singing, I lose the rhythm and it just goes down the drain. Can anyone suggest some methods to teach myself how to sing and play in unison? Taking formal lessons is not an option because I don't have the time or the funds to do it. Thanks.
Just practice over and over, its that simple.

Start with an easy song to start with, and pick a song you know by heart, like you can play without looking at the fretboard. Then just practice it until you get it.
When ever I'm learning a new song I sing it silently in my head while picking. Once I know it pretty good I start singing it out loud. It seems to work for me, give it a try.
Just try and time it out with your strums... your up and down strumming pattern goes with the count of the song for the most part, so just get down the particular words that meet up with the first strum of each new chord or major change, and focus on getting those words down by themselves. Sing it in your head a few times to get the timing down. It's much easier when the timing feels right
Singing & Playing

So you have a guitar and what you consider to be a decent voice. Now you’re asking yourself what you are going to do with these 2 things. Well, you’ve come to the right place. Here I will explain a few techniques that you can use to master singing and playing at the same time.

I am going to start with the guitar aspect of these 2 things. When singing while playing guitar, you are mostly playing chords or a simple riff. Not many people can shred guitar and sing at the same time, so don’t expect to do that. In fact, sometimes when playing live, Eric Clapton himself plays chords when he sings even though he is capable of playing anything out there.

So now you have all these chords figured out. Now the key is to be able to strum without singing first. You should figure out how the rhythm of the strumming goes along with the song. If you are doing a cover song, play with the recording. If it is an original song, then just play those chords.

Now if you have the strumming part down pat, and you can do it in your sleep, try to sing the song you are doing without playing guitar. Now same with the guitar part, if you are doing a cover song, sing along with that. If it is original, try singing it just solo. You should have the words memorized by this point. By having the words memorized, you don’t have to really pay attention to them anymore. Also, have the dynamics of the song down if there are any. Dynamics are really what make a song all the better.

By this point, you have the guitar chords memorized, and your lyrics to the song are basically memorized. Now they don’t have to be all perfect, as you are going to sing and play some more when putting it together. So it will come all together in the end. However, it’s good to have an idea of what you are doing. Now for this part there are 2 methods that I will recommend when putting it all together.

-Method 1 - Sing through the song 1 full time, just singing, then for the second time through, play each chord once whenever it is said to be played. With doing this, you will get a feel for playing and singing at the same time. This method works mostly on the voice, but adds the chords for a good feel of the song and how it should be. Once you do this a few times, you
are likely ready to add the strumming to the mix. If you can’t get all the way through the song, then look at what you are doing wrong, and make adjustments. Whether this be just going over the chords again, or the singing. The key is to take this slow when you are just learning how to sing and play at the same time.

-Method 2 - Play the song through just strumming just the chords. Then next time through, it’s easiest to just hum the words so you get a good feel of the song and the tune. You can do this several times if needed, or just a few until you get the feel of the song. From there, you can go all out with strumming and singing.

These are only 2 methods that I find work quite well. There are obviously many more and you can mix it up to get the maximum benefit. For more experienced singers, I recommend method 1. For more experienced guitar plays, I recommend method 2.

So now that you are able to sing and strum the guitar at the same time. Congratulations on that first off. Not many people are capable of doing his. So now you wonder what you can do with this. Well you must play of course. Now here are a few bands/artists that I have picked out that are perfect for not only practicing playing and singing at the same time, but that are perfect for playing regularly.

-The Beatles
-Foo Fighters
-Jack Johnson
-John Frusciante
-City and Colour
-Our Lady Peace
-Sam Roberts
-Matt Costa

These people are just a few of the tons of artists out there. There is no limit to what songs you can play. Often times you can play to stuff like Led Zeppelin and Pink Floyd if you can find the chords for it. Also, for those of you that are involved with church, there are limitless things you can do. Playing worship music is about the best way to practice singing and playing as you know how the song goes already. It’s just a matter of plugging it all in.

So look around for what style you are into, and don’t be afraid to let your voice free. That’s what this is all about. Just letting go of all your inhibitions and singing and play guitar for the joy of not only yourself, but for people around you as well. You are opening a whole new world of music to yourself so all the best with it!

Start off with "Hear You Me" by Jimmy Eat World, its simple up and down strumming on the beat. I'm building off of that song to try and do others like you.

Best to ask in our only singing thread at the top of the page. So I'll close this, and then you can ask in there.
