MUSIC THEORY - 4


BEAT FORMULA



Each song has its own beat and the best way to tell us the song beat is by showing on the beginning of the song. Some songs can change the beat in the middle but the composer will tell us that from that part on, the beat will be changed. The beat is like a Statement. The composer tells us what will be the "tempo" or beat of his/her creation.





In the biguining of any song you will see a SIGN and it's not a Mathematical Formula that you will have to resolve. In the song we will see two numbers on the beginning of any music sheet. 


In songs we play in church only have the words and the chords. You can ask how can they play without knowing the beat? We have to follow the words. I’ll explain this later. 


Anyway these numbers are not a mathematic calculation that you have to do. It’s just a simple information about the song you just about to play. It means what note and the time unity of the bar lines (time frame). I’ll explain!! In other words.. The number on the top shows how many beats each bar line is going to have and the number on the bottom shows which note is going to last one beat. You’ll notice that 90% of the songs will have a 4 on the bottom number, meaning that the Quarter note will always value one beat. Let’s go for an example.. as I told you it seems complicated but it’s not.

This is an example of a beat formula:














·  Top number – (2) Tells the number of beats on each bar line.

·  Bottom number – (4) Tells which note figure will value one beat. In this example a Quarter Note.


Just take a look now. The song on our example would be like this on a music sheet: 2 beats for each bar line and the quarter note valuing one beat.














Thinking about the beat formula on the example we can tell that this song is a two beat song.. “Country music are normally a two beat song (2/4). You can feel the “Tum, tah, Tum, tah, Tum, tah, Tum, tah” or count the beat like |1..2..|1..2..|1..2..|1..2.| “.

Now I hope I won’t blow your mind.. but lets go further.. You can replace the Quarter Note for other notes, faster notes like Eiths and Sixteenths. Just look at the example and you will understand.. I hope.
The firts example shows that in two beats you will play four notes and in the second example you’ll play eight notes in the time frame of two beats.. That’s fast!! Just try to do it like this with your left hand you will do |1..2..|1..2..|1..2..|1..2.| and with right hand you will do |1,and,2,and|1,and,2,and |1,and,2,and |1,and,2,and | You play on the “number” and on the “and” fast.





Now try to do this other exercise with your left hand you will do |1..2..|1..2..|1..2..|1..2.| and with right hand you will do |1,2,3,4,5,6,7,8|1,2,3,4,5,6,7,8|1,2,3,4,5,6,7,8|1,2,3,4,5,6,7,8| faster!!!! I know it’s crazy fast.. If you can do it you can call yourself a Virtuoso a nice name for music freaks!! It takes lots of exercise to do it. But don’t give up.. You’ll only need these kind of music if you play is an orchestra or a really fancy concert hall.. that’s for pro’s and not for normal people like you and me.

After understanding the examples above you are able to move on and use/read any musical figure just by looking at them and telling how long each note is going to sound in each bar line, including pauses. Let me show you another example:



Two beat song ok? In the beginning we will repeat each measure four times just for you to understand. In your head, taping your computer or desk or using a metronome you’ll count: 
|1..2..|1..2..|1..2..|1..2.|Ok? Now look at the first Bar Line you’ll see a …….. Half Note meaning that you will Play and hold the note for 1..2.. two beats. Now stop and go back and use your voice |1..2..|1..2..|1..2..|1..2.| PaAh, PaAh, PaAh,PaAh. The sound of your voice must sound for two beats. Just repeat this exercise for 4X. Ok.. Let’s move one to the second measure: You’ll see a Quarter Note and a Quarter Pause correct? It means one sound of one beat and silence for one beat. Let’s go again |1..2..|1..2..|1..2..|1..2.| Pa.., Pa .., Pa .., Pa .. (Sound, silence, sound, silence). Repeat 4X.  Ok.. Now go back to the first measure and restart the song. Do not think about the third measure!!  Just repeat the first and second measures 4X but this time do the first and second measures together. If you don’t feel comfortable do it again. Ok.. Third measure: Do you think you can handle it? Here we go again: 
|1..2..|1..2..|1..2..|1..2.| Now is gonna get crazy.. You can add an “and” between beats 1 and 2. You will play the second note of the first beat in the “end” not in the END of the song but in the “end” between them try it: |1 and 2 and |1 and 2 and |1 and 2 and| so it goes: |PA, pa, pa, pa, pa, pa| these last four sound are faster just because they are 16ths notes. It’s just a question of dividing the beat by its half.

    Ok This is the most complicated part of music.. but it’s the logical part. If you understand this logic you will be able to read any music in the world. Just try it hard.. slow down the beat, literally. Start with a 60bpm beat, very slow.. try again and again.




NOW LET’S PUT THIS INTO PRACTICE!

    Think of the seconds of a clock equals to one beat, lists just the Tic, not the Tac. Tic.., Tic.., Tic.., Tic.. Ok every two seconds we have a Bar Line. Using our Musical Formula the Quarter note will sound for each second of your clock (Tic). Now if you “play” on the (Tic, Tac) You are dividing the beat for two, correct? That’s the bear for a 8th note. Do this exercise clapping your hands.. See I told you.. People will think you are crazy!! But that’s Ok. It’s for a good reason.

Clap your hands on the “Tic” of your clock.. good. You got your Quarter Note beat. Now double the clap of your hands.. Clap on the Tic and on the Tac (Tic,Tac, Tic,Tac, Clap, clap, Clap, clap, Clap, clap,) you got a 8th beat. Now faster.. double the beat.. you got your 16th. Fast but very usefull.
This theory will never change Music is created and played using it. But as I told you.. If you practice you will do it naturally. It’s like Reading any language.. you have to learn the alphabet than put the leters together and make it sound like a word, words together will make a sentence, sentences together will

The most important thing is for you to understand the meaning of Half or Double and you’ll be a amazing musician. If you didn’t understand please do not go further.. stop and redo it.
There are others formulas for beat. We saw a 2/4 beat, there is also 3/8, 4/4 and others more complex beats formulas. The most common beats are 4/4 used on Ballads and Rock’n roll songs, ¾ used on Waltz, 6/8 used on slow songs etc. It’s better to show yu some examples of songs on each specific beat:

2/4 song: I wish i was in Dixie

BAR LINES


They are important on music writing just because they divide the song into groups of beat. It’s your time frame. It’s where the song is defined by the composer. What you are supposed to play in that period of time (beat).
When we listen to a song and we snap fingers or clap our hands or even stamp our foot what we are doing is very simple.. we are “playing” the song beat you are naturally feeling the music beat and you are just following the musicality that is inside you. It’s a natural instinct. Some people has more difficulty to follow the beat.. but if you try hard to listen to the sound of the drum kick (TUM) or snare (TAH) you will make it.

The beat can be different for each style of music.. Country music are normally a two beat song (2/4). You can feel the “Tum, tah, Tum, tah, Tum, tah, Tum, tah” just like this:

|1..2..|1..2..|1..2..|1..2.| 

When we listen to a Waltz we hear “Tum, tah, tah, Tum, tah, tah, Tum, tah, tah” you will count |1..2..3..|1..2..3..|1..2..3.| that’s a three beat song (3/4). 

When we listen to romantic or rock’n roll we normaly listen to a 4/4 song you will count |1..2..3..4..|1..2..3..4..|1..2..3..4..|1..2..3..4.| Notice that the first beat is always stronger than the others. It’s just a way to establish the first beat on that time frame. 

There are some songs that has a different beat like 5, 6, 7 or 12/8 but they are more complex jazz and experimental music, some techno crazy music. 

This is an example of something without bars. It’s just a sequence of 32 random stars doesn’t mean much:

********************************


Now look at the example of 32 stars divided with bars:

|****|****|****|****|****|****|****|****|


Much more organized and easy to follow, don’t you think so?!

So the bar lines are made to divide the beat and it will make Reading easier..




I hope you enjoyed this topic.

MUSIC THEORY - 2




MUSIC NOTATION - WRITING AND READING


Music writing and Reading is as important as playing any instrument. Some people has a amazing ability to play any instrument without formal studying. We call those guys “self-taught” musicians. They can play but sometimes they play in their own positions and styles, this can cause a serious musical and physical limitation to the musician. But sometimes when they are really good, rarely special, we call them “Virtuosos”  
Music reading is made of elements that are used for music writing just like our alphabet (ABCDE..) in music we use: Notes, Pauses, Cliffs, Signs. With these elements we can write music in a sheet of paper called “pentagram” a pentagram is a group of five lines and four spaces where we write music. Just like as a notebook has many lines a musical sheet also has lines to help us on our “musical” composition, or essay. Just for your curiosity: Penta means Five and Gram means Lines. It’s a Latin word.


Just to make sure I told you everything.: A pentagram can have more lines than the existing five lines. It goes down or up so you can have lower or higher notes on the pentagram.. we’ll see that in the future. Don’t worry. If you learn to read music, you’ll be able to play any instrument. That’s why is so important to learn it.

MUSICAL SIGNS OR FIGURES


Those guys help us figure out how long we are supposed to hold (play) that note. It’s what musicians call SOUND DURATION or SILENCE DURATION. When it sounds we call them NOTE when doesn’t sound we call them PAUSE. These figures are just like coin$$, you know how much each coin values by its figure, color, shape, size, (one cent is small and red for example). They are different for many reasons.. to make it easier to count or to blind people can recognize each coin’s value. When a note is played in any instrument or object, when this action of playing vibrates the material we call these notes as POSITIVE FIGURES, positive is good, up and is on, it has sound and vibrates. When the note is not playing, vibrating we call it PAUSE or NEGATIVE FIGURES, no sound, silence, zero.. off. So we only have two positions: ON and OFF just like in computer programming this is called BINARY LANGUAGE. The switch is ON or OFF.


Each note (Positive Figure) has it’s pause (Negative Figure) and they are equivalent, they have the same time value, but one is ON and the other is OFF. Just check this chart it will help you to see how they look like.

These are the most used ones:






All you have to understand now is very simple:

You have to think music notes as coins: $1.00 coin can be compared to a WHOLE NOTE. $0.50 will be a HALF NOTE. $0.25 equals a QUARTER NOTE in music we also have an EIGHTH NOTE and the SIXTEENTH NOTE, there is no similar in coins for these two notes. TIME in music is also money.. no I’m joking. In music Time as a figure, is visual and they look like those notes above. So.. Let’s do an exercise here:

Think about a 4/4 song. It means that in each measure “time frame” of four beats you can have: A WHOLE note witch is the longest note and you will hold the sound for four beats like this (You Play and hold 1…2…3…4… for four beats). You can also have two HALF notes instead of a WHOLE note the only difference is that you will play two notes instead of one note in that space of time (bars) or time frame (You Play and hold 1…2… play and hold 3…4…). You can also have four QUARTER notes in the time frame you will (play 1… play 2… play 3… play 4…). Or you can have a Half Note and two quarters note (You play and hold 1..2.. play 3.. play 4) or you can have two Quarter notes and one Half note (You play 1.. play 2.. play 3..4..) can also have eight notes on the time frame of four beats and also sixteen notes in the same time frame.. WOW! That’s fast!!

Just take a look at this chart and you will understand the difference.



That's all for now.. I really hope that you are enjoying reading this material as I am enjoying to write it. Just leave a comment so I can see if I'm going in the right direction.
