Interval (music)

Play Example: Perfect octave on C in equal temperament and just intonation: 2/1 = 1200 cents. Play The size of an interval (also known as its width or height) can be represented using two alternative and equivalently valid methods, each appropriate to a different context: frequency ratios or cents. The size of an interval between two notes may be measured by the ratio of their frequencies. Mathematically, the size in cents of the interval from frequency f1 to frequency f2 is Main intervals from C. Play In Western music theory, an interval is named according to its number (also called diatonic number) and quality. Perfect Perfect intervals on C. Perfect intervals are so-called because they were traditionally considered perfectly consonant,[10] although in Western classical music the perfect fourth was sometimes regarded as a less than perfect consonance, when its function was contrapuntal.

The Interactive Circle of Fifths ("the Circle" for short) is a tool designed to help musicians to: figure out the key of a piece of music easily transpose music to a different key compose new music understand key signatures, scales, and modes The concept of the circle of fifths is not a new one (see this Wikipedia article for more information), but there is more to this simple, yet profound structure than the traditional diagram can easily convey.

Interactive Circle of Fifths User's Guide

The Interactive Circle of Fifths goes beyond the limitations of a static diagram without sacrificing clarity and simplicity. This User's Guide will help you get the most out of the Circle, while introducing some basic music theory concepts. However, this is not intended to take the place of an introductory music theory course.

How to Read the Circle of Fifths

A major key and its relative minor use the same key signature, which means they use the same sharps (indicated as #) and flats (shown as b) in their scales. When you read the circle of fifths, you'll notice that the major keys are on outside of the circle. Opposite them, inside the circle, are their relative minor keys. At the top, you have the key of C major, which has no sharps or flats in its key signature. Each stop on the circle as you go clockwise from C is a key with one more sharp than the previous key. Use the circle of fifths to understand the relationship between major and minor keys. So, if you have the circle of fifths memorized (or have a picture of it handy), you can easily figure out what key a song is in.

Teoría - Music Theory Web. The Diatonic Scales. Music Modes. Home » Piano Theory » Music Modes , The story of the musical modes starts in ancient Greece.

Music Modes

The Greeks were the one to name the different modes after ancient Greek subgroups; the Locrians and the Dorians. Phrygia and Lydia were places with non Greek people close by. Later in the 9th century the church modes originated. Theorists took the Greek modes and applied them to their own concept. As time went on the music modes became less popular and composers preferred to stick to the Major and Minor scales for the concept of harmony has changed from being modal to being Diatonic. So why do I bother at all explaining you about the music modes if they weren't used so often as time went by.

Well, that's because the modes are a great tool to use when improvising. Musical Scales. C Major Scale (no sharps or flats) C D E F G A B C G Major Scale (1 sharp) G A B C D E F# G D Major Scale (2 sharps) D E F# G A B C# D.
