Fret in the context of "Fingerboard"

A lute (/ljuːt/ or /luːt/) is any plucked string instrument with a neck and a deep round back enclosing a hollow cavity, usually with a sound hole or opening in the body. It may be either fretted or unfretted.

More specifically, the term "lute" commonly refers to an instrument from the family of European lutes, which were themselves influenced by short-necked lutes in Gandhara (modern-day Pakistan) which became the predecessor of the Islamic, the Sino-Japanese and the European lute families. The term also refers generally to any necked string instrument having the strings running in a plane parallel to the sound table (in the Hornbostel–Sachs system).

The oud (/uːd/ OOD; Arabic: عُود, romanized: ʿūd, pronounced [ʕuːd]) is a Middle Eastern short-neck lute-type, pear-shaped, fretless stringed instrument (a chordophone in the Hornbostel–Sachs classification of instruments), usually with 11 strings grouped in six courses, but some models have five or seven courses, with 10 or 13 strings respectively.

The oud is similar to other types of lute, and to Western lutes which developed out of the Medieval Islamic oud. Similar instruments have been used in the Middle East, some predating Islam, such as the barbat from Persia. Different versions of the oud are used in Arabia, Turkey, and other Middle Eastern and Balkan regions. The oud, as a fundamental difference with the western lute, has no frets and a smaller neck. It is the direct successor of the Persian barbat lute. The oldest surviving oud is thought to be in Brussels, at the Museum of Musical Instruments.

The pipa (Chinese: 琵琶; pinyin: pípá; Wade–Giles: p'i-p'a) is a traditional Chinese musical instrument belonging to the plucked category of instruments. Sometimes called the "Chinese lute", the instrument has a pear-shaped wooden body with a varying number of frets ranging from 12 to 31. Another Chinese four-string plucked lute is the liuqin, which looks like a smaller version of the pipa. The pear-shaped instrument may have existed in China as early as the Han dynasty, and although historically the term pipa was once used to refer to a variety of plucked chordophones, its usage since the Song dynasty refers exclusively to the pear-shaped instrument.

The pipa is one of the most popular Chinese instruments and has been played for almost two thousand years in China. Several related instruments are derived from the pipa, including the Japanese biwa and Korean bipa in East Asia, and the Vietnamese đàn tỳ bà in Southeast Asia. The Korean instrument is the only one of the three that is no longer widely used.

The bouzouki (/buːˈzuːki, bʊˈ-/, also US: /bəˈ-/; Greek: μπουζούκι [buˈzuki]; plural. bouzoukis or bouzoukia, μπουζούκια) is a musical instrument popular in West Asia (Syria, Iraq, Lebanon, Cyprus), Balkans (Greece, North Macedonia, Bulgaria) and Turkey.

It is a member of the long-necked lute family, with a round body and a long neck with a fretted fingerboard. It has steel strings and is played with a plectrum, producing a sharp metallic sound, reminiscent of a mandolin but pitched lower. It is the precursor to the Irish bouzouki, an instrument derived from the Greek bouzouki that is popular in Celtic, English, and North American folk music.

The yaylı tambur is a bowed long-neck lute from Turkey. Derived from the older plucked mızraplı tambur variant of the Turkish tambur, it has a long, fretted neck and a round metal or wooden soundbox which is often covered on the front with a skin or acrylic head similar to that of a banjo.

The instrument is held vertically, with the soundbox resting in the player's lap or between the calves or it can be worn on a strap. The bow is grasped sideways, with the little, ring and middle fingers pressing on the horsehairs, while the thumb and index fingers hold the rightmost wooden edge of the bow or it can be held overhand like a Cello Bow to allow for more expressiveness. The leftmost strings of the instrument unite into a single course to form a doubled-string which is tuned to a unison that is lifted slightly from the bridge. This is where all melodic playing takes place. The rest are sympathetic strings numbering from 4 to 6 which are tuned to the octave, fifth and/or fourth of the main doubled-string.

The viola da gamba (Italian: [ˈvjɔːla da (ɡ)ˈɡamba, viˈɔːla -]), or viol, or informally gamba, is a bowed and fretted string instrument that is played da gamba (i.e. "on the leg"). It is distinct from the later violin, or viola da braccio; and it is any one of the earlier viol family of bowed, fretted, and stringed instruments with hollow wooden bodies and pegboxes where the tension on the strings can be increased or decreased to adjust the pitch of each of the strings. Although treble, tenor and bass were most commonly used, viols came in different sizes, including pardessus (high treble, developed in 18th century), treble, alto, small tenor, tenor, bass and contrabass (called violone).

These members of the viol family are distinguished from later bowed string instruments, such as the violin family, by both appearance and orientation when played—as typically the neck is oriented upwards and the rounded bottom downwards to settle on the lap or between the knees.

A fretless guitar is a guitar with a fingerboard without frets, typically a standard instrument that has had the frets removed, though some custom-built and commercial fretless guitars are occasionally made. The classic fretless guitar was first pioneered in 1976 by Turkish musician Erkan Oğur. Fretless bass guitars are readily available, with most major guitar manufacturers producing fretless models.

On the fretless guitar, the performer's fingers press the string directly against the fingerboard, as with a violin, resulting in a vibrating string that extends from the bridge (where the strings are attached) to the fingertip instead of to a fret.

The bass guitar, also known as the electric bass guitar, is the lowest-pitched member of the guitar family. It is similar in appearance and construction to an electric guitar but with a longer neck and scale length. The electric bass guitar most commonly has four strings, though five-, six-, and seven-stringed models are also built. Since the mid-1950s, the electric bass guitar has often replaced the double bass in popular music due to its lighter weight, smaller size and easier portability, most models' inclusion of frets for easier intonation, and electromagnetic pickups for amplification.

The electric bass guitar is usually tuned the same as the double bass, corresponding to pitches one octave lower than the four lowest-pitched strings of a guitar (typically E, A, D, and G). It is played with the fingers and thumb or with a pick.
