![]() ![]() The final 13th note is the octave note, having the same name as the starting note. In this case, the first explanation above applies - we will continue to use flat notes ascending and descending to match the scale. An example F chromatic scaleįor this example - the chromatic scale in the key of F, let's assume that we are working with a key that is on the circle of 5ths - F major scale, which is a flat-based key signature, and we want to identify some chromatic scale notes outside that key. when playing the notes from lowest to the highest pitch, then use flats when descending. Composers may use the scale in its entirety, use sections of it or even write long passages that use the scale extensively. Chromatic scales without a key signatureįor both C major key signature and A natural minor key signature, there are no sharp or flat notes, so since there is no key signature, we have no clue as to whether to use sharp or flat names to identify any non-natural notes.Īlthough there seem to be no generally agreed rules on how to handle this, one common music theory convention is to use sharps when ascending the scale ie. The chromatic scale is a composition tool often used by composers to create a sense of sadness or tension in a piece of music. Eb major key signature, where flat note names would be used. The same principle applies to flat-based key signatures, eg. All 12 notes are thus given more or less equal importance, and the music avoids being in a key. G major key signature, and we want to use the chromatic scale to identify notes outside that scale, sharps would be used for those chromatic scale notes. The technique is a means of ensuring that all 12 notes of the chromatic scale are sounded as often as one another in a piece of music while preventing the emphasis of any one note 3 through the use of tone rows, orderings of the 12 pitch classes. major scale, or any minor scale), then the key signature will be the guide as to whether to use sharps or flats for the chromatic scale.įor example, if a sharp-based key signature is used, eg. If chromatic scale notes are being used and identified within the context of a scale with a key signature (eg. Chromatic scale naming in the context of a key signature When it comes to naming the notes shown in the last step, the decision to be made is whether to use sharp or flat note names, both ascending or descending. This step gives note names to the piano keys identified in the previous step. ![]()
