Dissonance within music
 

I know about tritones , augmented chords etc. But i just dont know where to put them for the best effect.
any help?

You can use them anywhere. You can either throw a dissonant chord in here or there, or you can write progression revolving around them. Go listen to some king crimson. They use all sorts of errie dissonant chords most times for many passages.

Check this out, it should help.

Basically dissonance is the tension or unstable state of a chord which has a need to resolve to a stable (consonance) state. Kinda like unstable atoms, it has properties & characteristics in both states.

...this was a spambot?

Does anyone here know of any pieces where the minor second interval is used (I don't know if that is the right nomenclature but what i mean is: C and C# when the key is C)
Could some one also post some chords that use this interval (bear in mind that it HAS to be in the key of the lower note of the two)

If you're playing out of the fifth mode of the harmonic minor, you use a minor 2nd interval quite alot. It draws alot of resolution to the root of the mode. Also half-whole diminished uses a minor 2nd interval as well. Chords.... minor 9th's use the minor 2nd interval.

Thanks.

Strictly that should be Db, not C#.
You're talking about some kind of phrygian key, and there are few possible variants:
Phrygian: 1-b2-b3-4-5-b5-b7
Phrygian dominant (aka major phrygian or spanish phrygian): 1-b2-3-4-5-b6-b7
Phrygian natural 6: 1-b2-b3-4-5-6-b7 (6th mode of melodic minor)
Double harmonic: 1-b2-3-4-5-b6-7

A good example of ordinary phrygian is Pink Floyd's "Set the controls for the heart of the sun" (E phrygian, moves to A phrygian and back).

For double harmonic, try Dick Dale's "Misirlou"
7b9 chords are quite common in jazz, but the b9 will not usually be very low in the chord (although it might be a half-step above a high root).
A jazz phrygian modal chord is a susb9: 1-4-5-b7-b9 - again with the b9 well above the root (normally).

In short, the kind of chord you're looking for is not part of normal harmonic usage - which doesn't mean you can't create one if you want!

my band uses dissonant chords to accent riffs occasionally, and the dissonance resolves to consonance quickly after.
