![]() The more accidentals there are in the key, the messier the score would get. Firstly, a score with lots of accidentals in it is messy and harder to read. Why not just write the accidentals into the score? There are two main reasons for this. This means that whenever you encounter F or C in the score, you must remember that they are actually F-sharp or C-sharp. For example, if a piece of music is in the key of D major, it will have an F-sharp and a C-sharp in the key signature. We use key signatures to show what sharps or flats will be present in the score without having to clutter the score itself with an accidental sign in front of each relevant note. These are shown in the key signature, which is found at the beginning of each stave. All major scales except C major have one or more sharps or flats. Let’s look at C major on the piano first:īecause the sequence of intervals must always remain the same, no two major scales will ever have an identical set of notes. If we observe how the scale of C major is played on the piano, and then on the cello, we can actually see the difference between the whole tones and semitones. They are made up of a sequence of whole tones and semitones as follows: C – D = a whole tone or major second C – D-flat = a half tone or minor second) The structure of Major ScalesĪll major scales – no matter what note they begin on – follow the same structure. *** Interval: the pitch distance between 2 consecutive notes (e.g. ** Score: a written or notated representation of music * Times signatures, unlike clefs and key signatures, are only shown at the start of the first stave and do not appear again unless there is a change of time signature in the music Each type follows a specific order of intervals*** There are 3 main types of scales: major (which represent major keys), harmonic minor and melodic minor (which represent minor keys). A scale of one octave covers eight steps but since the first and eighth steps are the same note, there are only seven individual notes as mentioned in definition 1. ![]() Scale: a representation of the notes belonging to a key in ascending and/or descending order starting and ending on the key note (i.e.Instead, they follow the order in which they appear from one scale to the next. ![]() The order of accidentals in a key signature does not always follow the order in which they appear in the scale. These are shown at the start of each stave just after the clef and just before the time signature* and greatly reduce the number of accidentals that have to be shown in the main body of the score**. Key signature: a representation of the accidentals found in a key. ![]() Every key has 7 individual notes which are represented in the scale (see definition 3) of the key. A key can be major or minor and is represented by a key signature (see definition 2).
