While the minor second and major second, at 100 and 200{{c}}, respectively, are the same as that of 12edo, 24edo also has another kind of second halfway between the two, called a "neutral" second. This can serve as both a narrow whole tone and a wide semitone depending on how it is used. It is heavily used in [[Arabic | While the minor second and major second, at 100 and 200{{c}}, respectively, are the same as that of 12edo, 24edo also has another kind of second halfway between the two, called a "neutral" second. This can serve as both a narrow whole tone and a wide semitone depending on how it is used. It is heavily used in [[Arabic, Turkish, Persian]], and other forms of Eastern music as well as some east Asian scales though normally is slightly sharp or flat from 24et. The character of the neutral tone resembles the sound of bells, a car horn, and other sounds that are normally considered "non-musical" which can be a valuable asset to those trying to impressionistically compose music to mimic sounds such as trains and car horns. In fact, the dialling tone in the US is fairly close to a 150{{c}} neutral tone so one could potentially (and humorously) call it a "dial tone". In addition to all this, the neutral tone is surprisingly useful in chord progressions. An example of a neutral second is C–D{{demiflat2}}. | ||
