Anyone who composes, conducts, or performs music may also be referred to as a musician.   - An electric guitar is a fretted string instrument that uses a pickup to convert the vibration of its stringswhich are typically made of steel, and which occurs when a guitarist strums, plucks or fingerpicks the stringsinto electrical signals. The vibrations of the strings are sensed by a pickup, of which the most common type is the magnetic pickup, which uses the principle of direct electromagnetic induction. The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker, which makes a sound loud enough to hear. The output of an electric guitar is an electric signal, and the signal can easily be altered by electronic circuits to add "color" to the sound or change the sound. Often the signal is modified using effects such as reverb and distortion and "overdrive", with the latter being a key element of the sound of the electric guitar as it is used in blues and rock music.  - A minstrel was a medieval European entertainer. Originally describing any type of entertainer such as a musician, juggler, acrobat, singer or fool, the term later, from the sixteenth century, came to mean a specialist entertainer who sang songs and played musical instruments.  - The masenqo ( also spelled masenko , mesenqo , mesenko , masinko , or masinqo ) is a single - stringed bowed lute commonly found in the musical traditions of Ethiopia and Eritrea . As with the krar , this instrument is used by Ethiopian minstrels called azmaris ( `` singer '' in Amharic ) . Although it functions in a purely accompaniment capacity in songs , the masenqo requires considerable virtuosity , as azmaris accompany themselves while singing .  - The lyre ("lýra") is a string instrument known for its use in Greek classical antiquity and later periods. The lyre is similar in appearance to a small harp but with distinct differences. The word comes via Latin from the Greek; the earliest reference to the word is the Mycenaean Greek "ru-ra-ta-e", meaning "lyrists" and written in the Linear B script. The lyres of Ur, excavated in ancient Mesopotamia (modern Iraq), date to 2500 BCE. The earliest picture of a lyre with seven strings appears in the famous sarcophagus of Hagia Triada (a Minoan settlement in Crete). The sarcophagus was used during the Mycenaean occupation of Crete (1400 BCE). The recitations of the Ancient Greeks were accompanied by lyre playing.  - Eritrea (or ), officially the State of Eritrea, is a country in the Horn of Africa. With its capital at Asmara, it is bordered by Sudan in the west, Ethiopia in the south, and Djibouti in the southeast. The northeastern and eastern parts of Eritrea have an extensive coastline along the Red Sea. The nation has a total area of approximately , and includes the Dahlak Archipelago and several of the Hanish Islands. Its toponym "Eritrea" is based on the Greek name for the Red Sea, which was first adopted for Italian Eritrea in 1890.  - The krar or kraar is a five- or six-stringed bowl-shaped lyre from Eritrea and Ethiopia. The instrument is tuned to a pentatonic scale. A modern "krar" may be amplified, much in the same way as an electric guitar or violin.
