Acoustic guitar learning help?

Question:I'm teaching myself guitar. It's a Classical Spanish Acoustic Guitar, and I've been playing for about three weeks.
I've been making some pretty good progress, but theres one thing that is bugging me.
Whenever I play a song, and I press down on the strings, whenever I release the string, it always makes a noise.
And you can hear it, and the song doesn't sound as good.
Like, I'll press the string down, pluck the note, release to move on and then theres this annoying soft 'twang' from when I released the string.

Also, one other thing. Am I holding the guitar wrong? After I play for a little while, on my hand that is at the neck of the guitar, my wrist starts to hurt and cramp up. I know that you're supposed to keep your wrist straight, but I have a pretty small hand and in order to reach all the frets, hold the guitar up and still move around, I need to bend my wrist a little.

Anybody know the answers to either of my concerns?

Proper form for your left hand is to keep it straight, with your thumb straight on the back of the neck in opposition to your index finger. You should technically never curve your thumb over the top of the neck. HOWEVER, it really is a matter of what is comfortable for you to some extent. You have been playing three weeks. Hardly enough time to figure out how to do things wrong yet. Stick with the program for awhile. You will adjust to it and it will be like riding a bicycle after awhile.

As for the twang? That could be a function of releasing the strings too slowly or the strings sort of sticking to your finger when you release. If you listen to many classical players, you will notice that sound when they move as well. Sometimes on the steel strings you will also hear a sound as if they are dragging a fingernail across the winding of the string. Of course, you want to minimize that. But it's not necessarily a sign of being a bad player.

Also, you have to remember that your fingertips are still soft and the strings may actually sink into the skin of your fingers. As you develop callouses, you should see this problem decrease if not totally go away.

Just keep practicing. You'll figure it all out. You'll find a grip that works for you. It's frustrating when you are learning. But if you practice the way you have been, it's all going to work out.

i guess classical is different cxause i was taught to bend my wrist and maybe your pushin to close to the frets
