Musical note commonly), a double sharp sign on a key signature with a single sharp indicates only a double sharp, not a triple sharp. Assuming enharmonicity, many accidentals will create equivalences between pitches that are written differently. For instance, raising the note B to B is equal to the note C. Assuming all such equivalences, the complete chromatic scale adds five additional pitch classes to the original seven lettered notes for a total of 12 (the 13th note completing the octave), each separated by a half-step. Notes that belong to the diatonic scale relevant in the context are sometimes called "diatonic notes";
In scale and containing notes between them, as in the "miyako-bushi" scale used in "koto" and "shamisen" music and whose pitches are equivalent to the "in" scale: In Indian classical music, Gunkali (Hindustani) and Karnataka Shuddha Saveri (Carnatic) are nearly identical to the pentatonic "in" scale, highlighting the shared past of their origins. Some rare examples of ancient genres of Andean music (e.g. k'antu) use a scale similar to the "in" scale combined with melody leading with a parallel fifths and fourths. For example listen to "Machulas Kantu" by Bolivia Manta folk group ("Wiñayataqui", 1981). In scale The in" scale (also known
