If you are a decent song writer:
 

okay, well i have been singing and performing over all for about 9 years, but i just always seem to get writers block when i try to write music.

im into the whole indie/acoustic scene and i would appeciate some help on how to write a song, thank you(:

...first rule; don't ever "try"

I have done a wee bit of songwriting... Well, just two or three songs, and I'm not ready to use they for anything yet. But I can't just sit down and write, what I have written so far just kinda came to me at random (dreams, etc.)

I have to agree with ocean and silence,dont try.It should come natural.Or drink a brew and reminis.Get your mind relaxed.

Write what you feel.

Write it how it is in your mind, don't try to rhyme or anything.

That's a little biased of me, since I hate rhyming, but it's true.

I would suggest a subject that you're passionate about.

I would suggest brainstorming if all else fails.

Do you read a lot?

Is is music or lyrics you're having trouble writing?

As for writing music, this is how I normally do it. I usually come up with a progression of base chords, for example a simple progression would be Em, C, G played in a loop. Then once I have discovered a progression of chords that I like, I start to mess around with them - break them up, play them in scales or arpeggios, play alternate versions of the chords, etc. A lot of writing music for me has to do with messing around until I discover a melody or progression I really like.

As for lyrics, they may start off as a string or words that I like. Then I might add to it a rhyming sentence, or another sentence that doesn't rhyme, or sing them to a melody that I like. As I said, for me personally a lot of writing music is just about messing around and building on things that I create until eventually they resemble a song.

Whoops, I based it solely on lyrics.

But I guess it applies, still.

lyrics can actually be made from just about anything: poems, experiences, dreams, fantasies, protest, love, hate, etc...

the list is endless

"Writers block" happens to everyone.

When it hits me, I just practice.

The best way I've found to practice is simpy to write stuff in a style similar to your existing "good" material - or, failing that, someone else's.

There's no shame in learning someone else's song note for note - every classical musician does that, as do jazz musicians.

It seem that in Rock music, people prize this non-existent ability to just write stuff with no prior experience.

Like I say, this does not exist.

If you are a composer, compose.

I have problems with stuff like this all the time . . . I'll come up with 3 or 4 really good lines and from there I'm S.O.L but I never throw away the bases I get . . . if you can do something like that, you can look back at what you've started and add on later . . .
