![]() All seven letters can be used once, and no letter can be used more than once. In diatonic music, each scale has seven pitches. Scale - a condensed ordering of all seven pitches in a diatonic pitch collection where all intervals are either minor 2nds or major 2nds.Diatonic music - tonal music that uses all seven letter names only once and follows a specific order of intervals.Tonal music - music organized around a central pitch.has a specific order of intervals that create a scale.The term diatonic can have a variety of meanings depending on context, but for this course, we will be using this term to refer to music that: It is these intervallic relationships that create pitch collections, and if that pitch collection has certain properties, it can be further categorized.įor the majority of this course, we will be discussing diatonic music which is a subset of tonal music. Once we have chosen a central pitch around which we build a tonality, every pitch in the tonality can be summarized by its relationship to that pitch. ![]() Tonal music is organized around a central tone called the tonic. ![]() For this course, we will be studying tonal music, because tonal describes the organizational method of this music. If we accept that music is “organized sound”, then the method used to organize it will define any style of composition. It also provides a great launching point for discussing pitch collections and scales. ![]() This is possibly the most succinct explanation that differentiates music from sound and/or noise. To begin our discussion, I asked for definitions of music. Lesson 2b - Scales and Scale Degrees - Diatonic, Pentatonic, and Chromatic Class discussion ![]()
