Quality is not a measure of how good something is in music, it refers to if the chord is major, minor, diminished, or augmented.įor example, the 3rd scale degree of the major scale is the major third. Intervals are important in terms of harmony as they define the quality of chords. A whole tone (aka whole step) spans two notes or two frets on a guitar string. the interval between A and A# is a semitone. The smallest interval is the semitone aka half step which is the interval between a note and the note nearest. the type of interval is defined by the distance between notes, not the notes themselves.Īn octave, as outlined above is a type of interval with 12 notes between. Whiles notes are absolute, intervals are relative e.g. Intervals differ from notes as they describe the distance between notes, defining the relationship and how a melody or harmony sounds. Other useful scales for guitarists include the minor pentatonic scale, blues scale, and natural and harmonic minor scales.Įach note of a scale is known as a scale degree. It is foundational to music in terms of harmony and is used as a relative scale for all other scales. In terms of music theory, the most important scale is the major scale. the notes played are derived from a specific scale (defined by the first note (tonic) of the scale and sound good when played over chords within the same key. The notes from scales can then be used to play in key, both harmonically (in the form of chords) or as single notes.

Scales are simply series of notes taken from the chromatic scale and placed in ascending or descending order. And while the chromatic scale is technically a scale, it contains all the notes used in music so isn’t as useful in terms of composing music as scales derived from the chromatic scale. ScalesĪs you can see, in the process of explaining music we’re simply breaking things down into smaller and smaller increments. Knowing the order of the chromatic scale is key to learning the fretboard. Most of the time you will come across sharps (#) being used when ascending in pitch and flats (b) when descending, however, when used in scales both can be used to prevent repeating a note letter. This means A# is of the same value as Bb, C# is of the same value as Db, and so on. They are enharmonic, which of the same value musically. The remaining 5 notes are accidentals e.g. 5 of these are natural notes and follow the order of the alphabet: A, B, C, D, E, F, G The chromatic scale contains all the available notes in our musical system. The notes simply follow the alphabet and are represented by the chromatic scale: A This is known as 12 tone equal temperament (12 TET ). You can read more about how that works here if interested, but what’s important to understand is that octaves are divided into 12 notes.
Octaves are divided into 12 equally spaced sections on a logarithmic scale. The next step in understanding how music works are to divide octaves into notes that we can use to make music. And, we also know that we can hear between 20 and 20,000 Hz and octaves are double the frequency of the octave below it. the number of completed soundwaves per second. We’ve been over what sound is and how the brain perceives it, how pitch is defined by frequency e.g. Musical Notes The 12 Tone Equal Temperament System There are 10 octaves between 20 and 20,000Hz. In simple terms, this means each octave is double the frequency of the one lower than it. If that number was doubled (512) or halved (128) the brain would recognize it as the same note. Take the note middle C, which is 256 Hz (256 soundwaves per second). If that sounds confusing allow me to explain. However, we hear frequencies that are multiples of the same frequency as the same note.
The human ear can detect sound between 20 and 20,000Hz (20Khz). This occurs because the length of the guitar string able to vibrate has been shortened, reducing its mass and allowing it to vibrate faster, increasing the note’s frequency, and therefore raising its pitch.
