When you listen to a piece of music you usually dont think of math, but the two are interlinked and music always involves math even though we dont always realize it. When musicians play music they are using mathematical formulas to play. There are formulas for making cords, scales and a formula for the what notes they play. Musical notation also involves math, you use time signatures while playing along to a piece of music which are basically just fractions, 3/4,7/4, and 4/4 are all time signatures. the bottom number in the fraction gives you the type of note to be played and the top gives you the amount of times it is played. There are five basic types of notes to be played in music, the sixteenth note, the eighth note, the quarter note, the half note, and the whole note. For each of these notes you divide the previous note by two. The sixteenth note is divided into two which gives us eight, the eight into four, and so on (see chart). The easiest note to start with is the whole note there is one beat per measure of a song, for the half there is two beats per measure, and so on until there is sixteen beats per measure.(www.tabcrawler.com)Guitar chords are also made using a formula, first you get the scale of the type of cord you are trying to form, for example lets say c-major the formula for making a major cord would be tone, tone, semi-tone, which would mean the first note in the scale, the fourth, and the seventh. This is how most musicians make a cord. The first note in the scale is always a full tone as is the last this is because this is two octaves apart and they are the root notes. (guitar player, June 1996)There are twelve tones in an octave ex. C, C#, D, D#, E, F, F#, G, G#, A, A#, B. A full octave would have another C at the end but it is the same pitch as the first C except an octave higher so it is usually left out. Ancient Greeks came up with this method, they said in an octave each note was an integer multiple of the f...
