The key name is confirmed by the semibreve (whole note) appearing after each signature. We illustrate below the sequence of key signatures that the circle of fifths produces in each case - moving clockwise for the sharp keys or anti-clockwise for the flat keys. In fact, the fourth degree of the scale is the same note as you would get by moving a 'fifth' down the major scale. You may be wondering why, if we use a circle of fifths, the flat keys are found by taking the fourth degree of the major scale. We have marked the number of flats for the first two flat keys. The key signature for each key has one flat more than the key preceding it in the sequence. Having done this the necessary number of times you will have produced the sequence C, F, B flat, E flat, A flat, D flat, G flat and C flat. Again moving anti-clockwise, place the fourth degree of the F major scale, the note B flat, in the ten o'clock position. Moving anti-clockwise, place the fourth degree of the C major scale, the note F, in the eleven o'clock position. Place the note C in the twelve o'clock position on a clock face. We have marked the number of sharps for the first two sharp keys The key signature for each key has one sharp more than the key preceding it in the sequence. Having done this the necessary number of times you will have produced the sequence C, G, D, A, E, B, F sharp and C sharp. Again moving clockwise, place the fifth degree of the G major scale, the note D, in the two o'clock position. Moving clockwise, place the fifth degree of the C major scale, the note G, in the one o'clock position. There is, however, a shorthand way of remembering the relationship between the key and the key signature using the circle of fifths (also called Heinichen's circle of fifths or cycle of fifths) illustrated below. Of course, we could work out the note row for each major key and so identify the number of sharps or flats in each key. We now need to determine the key signature for each of the major keys. What is Musica Ficta? - part of an article entitled Hexachords, solmization, and musica ficta.Alterations such as these were never written in the music but are an example of musica ficta which means, literally, "feigned music". The singers would alter these by flattening the B. Modes may contain intervals that are not pleasing to the ear. Before the end of the eighteenth century, composers still thought musically in terms of modes which would, for a particular key note, tend to have different number of sharps or flats associated with them than with our modern major and minor scales. One explanation is the association between 'key signatures' and the use of 'major' and 'minor' keys. This is found particularly when the music is written in a minor key. Music from the Baroque and earlier periods may be written with key signatures containing fewer sharps or flats than we might expect. On the first line the instrument name is written in full, while on the other line(s) it is abbreviated.Īs an aside, it is worth remembering that the concept of key signatures as we know it today developed in the latter part of the eighteenth century. The bars have been numbered 'line by line'. The time signature is written only on the first line, placed after the clef sign and key signature. The key signature appear on every line of music immediately after the clef sign. The key signature applies to all the relevant notes in every octave.Īs well as simplifying the notation, the key signature usually, but not always, tells us the key of the piece. If we write the A major key signature (three sharps), at the beginning of the stave, one no longer needs to place 'sharp' signs in front of these notes. If the notes are written with no key signature every 'sharpened' note must be marked with a 'sharp' sign. ![]() ![]() Examine the row of notes in the key of A major. In the previous lesson we touched upon a method for reducing the number of sharp and flat signs when writing music in a particular key.
