Mandolin are used. Usually, courses of 2 adjacent strings are tuned in unison. By far the most common tuning is the same as violin tuning, in scientific pitch notation G–D–A–E, or in Helmholtz pitch notation: g–d′–a′–e″. Note that the numbers of Hz shown above assume a 440 Hz A, standard in most parts of the western world. Some players use an A up to 10 Hz above or below a 440, mainly outside the United States. Other tunings exist, including "cross-tunings", in which the usually doubled string runs are tuned to different pitches. Additionally, guitarists may sometimes tune a mandolin to
Five string violin he first showcased his modification during his performance in Las Vegas. The components that make up a five string violin are very similar to those found on a traditional violin. The strings are typically tuned to the following pitches, given in scientific pitch notation: C3, G3, D4, A4 and E5. The shape of the body and neck of a five string violin closely resemble that of a traditional violin. The body may be slightly wider and deeper to improve the resonance of the C string. It features a larger pegbox to accommodate the fifth string. Although larger than a traditional
