i'm searching for any advice as possible to compose music... ideas apart..
is there a line to follow in order to build a song? many could tell me there isn't...
for example, in my case...what if i want raise a song? do i have to start form the intro...chords... i don't know.
actually i don't have a band so i cannot use the help of the singer, drummer or bass player...
i know i can do something good, but i need a kind of tech advice
It's not really weird to ask, I'm sort of in the same boat. Thing is, I can come up with riffs out the ass, but I can't seem to ever follow through with a full song without jamming with someone else, I don't know why. My guess is because I feel like nothing else following the riff I started with sounds as good as that riff, so I give up.
My best advice is if you come up with something you like, stick with it and just try to come up with ideas to go with it, and don't try to compare everything with the starting riff. Another thing that works (for me at least) is to just play. Just take riff you have that you really like, and just play. Don't TRY to create a song or anything around it, just through in some single-note passages and/or chords here and there with it. I've come up with entire songs almost doing that, the only problem is that I usually can't play it all back after I stop playing. I've forgotten a lot of sweet melodies because of that. If you do this, I recommend recording it all so you can play it back and keep what you like! I need recording gear...
I don't think there is a specific way to do it. I've never been told how to compose a song, neither I have any musical education, but when it comes down to it you need to have something to say in order to write a song. I written over 200 songs & don't remember once to think about how it would go. What you want to say will dictate how your song will develop. Of course after you write a lot of songs you can just do it riffing or following some "schematic", but it's not really a song after all, it's a joke.
Well first of all you have to be inspired by something. Secondly a good study of the musical modes and the mood and feeling each one generates will broaden your spectrum. Furthermore it will give you more drive and you'll play a lot more
My opinion is that the song should also work on an accoustic guitar. Surely this is not true for all kinds of music (Speed metal on a Martin ) - but for the style of music I do this is important.
Normaly I find a few nice accords which work good together. Then I start to think about the vocals (which are the most important in a song for my opinion). After this the song would be ready to be played unplugged. I think at this point it is important not to have spent too much thinking on technical details on guitar, drums,...
BUT... The accords will change into some strange heavy distortet riffing on my Herbert, and the drums will do some double bass which accents the guitars riffing for example... At this point I begin to get creative on the instruments.

it's not simple, yes
