In these primary considerations a view of some general aesthetic traditions common to much of East Asian music is also requisite. The tonal vocabulary of 12 tones generated in a cycle of fifths is the first common factor. From this tonal vocabulary various scales of five to seven notes are chosen. As in the West, the total number of notes in an East Asian scale is often seven, but each scale tends to have what could be called a five-tone (pentatonic) core. The one scale in which no half steps appear (the so-called anhemitonic pentatonic) is common all over the world, although casual listeners often mistake it as being characteristically “Oriental.” A few moments spent listening to authentic East Asian recordings will reveal clearly that the five black notes on the piano do not represent all the sonic resources of Asian music. Indeed, there are a great variety of East Asian musics. Some are historically related and others are indigenous. Their three most common characteristics are linearity, transparency, and word orientation.

Linearity means an emphasis on melodic tension and release supported by or held in further tension by rhythmic devices. This line-and-rhythm orientation and lack of interest in Western-style harmony are, in fact, major distinctions between most of the world’s music and that of the West. In traditional East Asian music, as well as in most other non-Western traditions, all melodic instruments play the same basic melody. No one fills in the texture with chords. If harmonic texture is used, its function is to provide colour rather than to generate tension or release by chord progression. Heterophony (more than one version of the melody being heard at the same time) may occur to enrich the line. The sense of moving through a time continuum toward an ending, however, is basically developed through the tension produced during the wait for a pitch to resolve to a pitch of rest just one tone above or below. In Western single line (monophonic) music one feels this melodic tension when, for example, in the key of C major the note B or D resolves to C. A Westerner may feel an additional sense of harmonic accompaniment in such an example. While such harmonic orientation is not part of traditional East Asian listening and although the scales and pitches may be different in East and West, this basic principle of melodic tension is the same.

Transparency refers to the preference in East Asian music for chamber-music sound ideals; no matter how large an ensemble may be, the individual instruments are meant to be heard. This differs from the orchestral sound ideal, popular in 19th-century Western music, in which the intention is to merge the sounds of the individual instruments into one musical colour. A transparent texture is a logical choice for a tradition that wishes to emphasize lines; orchestral colour helps to merge various lines into single vertical sonic events called harmony.

Word orientation refers to the fact that until the 20th century there was little abstract instrumental music, such as a sonata or a concerto, in East Asia. A piece had either a text or a title that evoked an image, such as Moon Over the River or Spring Sea. Perhaps this relates to a general sensitivity to nature in East Asian culture as a whole. Whatever its source, it has produced many sonorous and pleasing results.
