In harmony, quarter tones tend to be perceived as [[dissonant]]. As such, the [[harmonic entropy]] model is generally tuned to portray them as having the highest harmonic entropy of any interval. In melody, they tend to produce a "bending" or "melting" effect. Due to this effect, they are often used as grace notes to smoothen and add color to the transition between more distant intervals. | |||
In the classical and folk traditions of [[Arabic, Turkish, Persian|Arabia]], [[Indian|North India]], [[Indian|South India]], [[Arabic, Turkish, Persian|Iran]] and [[Arabic, Turkish, Persian|Turkey]], quartertones are not used as melodic intervals in their own right, but they are used as critical building blocks of larger melodic units. They are particularly used to build [[neutral]] intervals such as neutral seconds and neutral thirds (it should be noted that each of these traditions has multiple flavors of major, minor and neutral seconds, thirds, etc.) | In the classical and folk traditions of [[Arabic, Turkish, Persian|Arabia]], [[Indian|North India]], [[Indian|South India]], [[Arabic, Turkish, Persian|Iran]] and [[Arabic, Turkish, Persian|Turkey]], quartertones are not used as melodic intervals in their own right, but they are used as critical building blocks of larger melodic units.
