Kroncong (pronounced "kronchong"; , ) is the name of a ukulele-like instrument and an Indonesian musical style that typically makes use of the kroncong (the sound comes from this instrument, so the music is called kroncong). A kroncong orchestra or ensemble traditionally consists of a flute, a violin, at least one, but usually a pair of kroncongs, a cello in pizzicato style, string bass in pizzicato style, and a vocalist. Kroncong originated as an adaptation of a Portuguese musical tradition, brought by sailors to Indonesian port cities in the 16th century. By the late 19th century, kroncong reached popular music status throughout the Indonesian archipelago. Characteristics The name "Kroncong" may be derived from the jingling sound of the kerincing rebana, as heard in the rhythmic background of the music created by the interlocking of instruments playing on or off beat. This background rhythm runs faster than the often slow vocals or melody, and is created, typically, by two ukuleles, a cello, a guitar and a bass. These instruments, especially the pair of ukuleles, interlock as do the instruments in a gamelan orchestra, and it is clear that the musical traditions of Indonesia have been applied to an orchestra of European instruments. Previously, they also used the Portuguese musical instrument called cavaquinho, a four steel stringed musical instrument that looks like a guitar; however, cavaquinho was then modified into a prounga, a 3 nylon stringed instrument with low pitch, and a macina, a 4 nylon stringed instrument with high pitch. One ukulele, called the "cak" (pronounced "chak"), may be steel-stringed. The instrumentalist strums chords with up to 8 strums per beat in 4/4 rhythm. The off-beat strums are often accentuated. The other ukulele, called the "cuk" (pronounced "chook"), is larger and has 3 gut or nylon strings. The instrumentalist may pluck arpeggios and tremoloes using a plectrum, and the on-beat is emphasised. As a set, the cak and cuk form an interlocking pair that mostly gives Kroncong its characteristic kron and chong. The cello may have 3 gut or nylon strings and the chords are plucked rapidly, often with a unique skipped-beat using the thumb and one finger. This instrument then adds both rhythm and tone. The guitar may play similarly to either cak or cuk, but plays are often extended scalar runs that provide an undulating background to a chord or bridge chord changes. The bass is often played in
