Here is another short music lesson from tbotts music on how to calculate the notation of a diatonic major scale. The method for the calculation is the same for all the twelve major keys. The diatonic scale is made up of five whole tones and two semitones, from the tonic (first note) of the scale we have two whole tones, next we have a semitone, then three further whole tones finishing with a second semitone. We hope this lesson will be of use to all you aspiring piano players and may we take this opportunity to wish you many hours of happy piano playing!!!
