An Introduction
Browsing through the audio portal, I found that many of the audio submiters knew very little, if any music theory! This kind of disgusted me and I was a little sickoned by it because I knew that if those submiters knew even a little more music theory then they already did, their music would be SO much better!!! So what am I going to do about it??? I'm going to make a thread where I teach a little about what I know as a composer about theory (this thread). I mean my things to be very brief; to just touch on my different topics.
I didn't want to get TO advanced so all I will cover will be rhythm, pitches, enharmonics, intervals, key signature, scales, chords, how melodies fit with chords, and then secondary dominants. Not that hard, so let us begin!
Rhythm
Rhythm is the building block of all music. Without it, music would be one constant note that would go on forever. It is obvious that we have many notes played in are music (not counting the modernistic song "Silence" which is silence for two minutes and some seconds) so thus we have rhythm.
In music, rhythm is oranized in beats. How fast the beats are is determined by something we call tempo. The tempo of a piece tells how many beats per minute a certain piece of music will go. For instance, if the tempo for a piece is 160 (Allegro for you nerds out there) that would simply mean that there would be 160 beats per minute. Tempos can also change in between pieces.
Then there are different "note shapes" or symbols that represent how many beats a certain note would get. The basic rhythms are as follows. They are not that specific, but you can get more information elsewhere.
16th Note - filled circle with a line and 2 flags attached - 1/4 of a beat in 4/4 time
Eighth Note - filled circle with a line and a flag attached - 1/2 of a beat in 4/4 time
Dotted Eighth Note - filled circle with a line, flag attached, and a dot - 3/4 of a beat in 4/4 time
Quarter Note - filled circle with a line - 1 beat in 4/4 time
Dotted Quarter Note - filled circle with a line and a dot - 1 and 1/2 beats in 4/4 time
Half Note - Empty circle with a line - 2 beats in 4/4 time
Dotted Half note - Empty circle with a line and a dot - 3 beats in 4/4 time
Whole note - Empty circle - 4 beats in 4/4 time
Beats are then organized into measures. A measure is represented by a line through the staff. How many beats a measure gets is determined by a time signature. A time signature has two numbers to it; one on the top, and one on the bottom. The top note simply tells the person playing your music how many beats per measure there will be. The bottom note tells the person what note will equal one beat!
For the bottom number, a four means a quarter note, a two means a half note, an eight means an eighth note ect... Time signatures can also change
So as one last example for rythm... If you are in a 2/2 signature and you have an quarter note when the tempo is 120, the quarter will last for 1/4 of a second because a quarter note is half a beat in a 2/2 time signature and when there are two beats per second (because of the tempo being 120, you can do the easy math of .5 x .5.
Pitches
A notes pitch is how high the frequency of a certain note is. We tell the person reading your music what frequency to play by putting a ryhthm symbol (such as a half note) on a staff. A staff is a series of 5 lines placed perpendicular to each other.
On the staff you can write one of three basic (there are many wierd cleffs that I won't talk about like the "Alto Clef") different clefs. The three clefs are the Treble Clef, Viola Clef, and the Bass Clef. The bottem most line of the staff in Treble Clef is an E, for Viola Clef it would be a F, and for bass it would be a G. Going up to the next space you would get the next letter of the alphabet, and then going up to the next line would then bring to the next letter. However, when you reach G you will go back to the beggining of the alphabet at A.
Each advancing of a letter is what we call raising (or lowering) a full step (with the exception of 4 notes that I will explain in my next section "Enharmonics). To raise it by a half step you put a sharp behind the note which looks like this: #. To lower it by a half stem you put a flat that looks like this: b.
I know this section has been a little brief, but I hope you get what I am trying to say. For more information about pitches feel free to do a Google search.
Enharmonics
Enharmonics is very simple, but can be confusing to some people so listen up! Before I teach you enharmonics, I have to tell you that the exception of whole steps, which I mentioned earlier, is between E and F and between B and C. They are half steps.
So, enharmonics is simple. An enharmonic, is a note that has two names with the same sound. For instance, C# and Db are enharmonic because they have the same sound. Think: 0 + .5 = 1 - .5. I hope you understood that.
Now why I had to mention the exception is because I had to tell you (because of when you learn scales and chords later in this thread) E# is enharmonic to F. Think: 0 + .5 = .5.
