Career

Music

Pre-debut

Thunder was born in Busan, South Korea but grew up in the Philippines, where his eldest sister, Sandara Park, achieved nationwide fame in 2004 after winning 2nd place in a talent search reality competition. He first appeared on national television when he attended the finale with his mother. Later on, as his sister began her hectic activities as a celebrity, a crew from one of South Korea's biggest TV agencies recorded her daily life in the documentary My Name Is Sandara Park. This marked Thunder's first ever appearance on Korean TV.

Thunder

Thunder is the sound caused by lightning. Depending on the distance and nature of the lightning, thunder can range from a sharp, loud crack to a long, low rumble (brontide). The sudden increase in pressure and temperature from lightning produces rapid expansion of the air surrounding and within a bolt of lightning. In turn, this expansion of air creates a sonic shock wave, similar to a sonic boom, which produces the sound of thunder, often referred to as a clap, crack, or peal of thunder.

Cause

The cause of thunder has been the subject of centuries of speculation and scientific inquiry. The first recorded theory is attributed to the Greek philosopher Aristotle in the fourth century BC, and an early speculation was that it was caused by the collision of clouds. Subsequently, numerous other theories were proposed. By the mid-19th century, the accepted theory was that lightning produced a vacuum.

In the 20th century a consensus evolved that thunder must begin with a shock wave in the air due to the sudden thermal expansion of the plasma in the lightning channel. The temperature inside the lightning channel, measured by spectral analysis, varies during its 50 μs existence, rising sharply from an initial temperature of about 20,000 K to about 30,000 K, then dropping away gradually to about 10,000 K. The average is about 20,400 K (20,100 °C; 36,300 °F). This heating causes a rapid outward expansion, impacting the surrounding cooler air at a speed faster than sound would otherwise travel. The resultant outward-moving pulse is a shock wave, similar in principle to the shock wave formed by an explosion, or at the front of a supersonic aircraft.

Singing

Singing is the act of producing musical sounds with the voice, and augments regular speech by the use of tonality, rhythm, the use of sustained tones and a variety of vocal techniques. A person who sings is called a singer or vocalist. Singers perform music (arias, recitatives, songs, etc.) that can be sung without accompaniment or with accompaniment by musical instruments. Singing is often done in a group of other musicians, such as in a choir of singers with different voice ranges, or in an ensemble with instrumentalists, such as a rock group or baroque ensemble. Singers may also perform as soloist with accompaniment from a piano (as in art song and in some jazz styles) or with a symphony orchestra or big band. There are a range of different singing styles, including art music styles such as opera and Chinese opera, religious music styles such as Gospel, traditional music styles, world music, jazz, blues and popular music styles such as pop and rock.

Singing can be formal or informal, arranged or improvised. It may be done for religious devotion, as a hobby, as a source of pleasure, comfort, or ritual, as part of music education, or as a profession. Excellence in singing requires time, dedication, instruction, and regular practice. If practice is done on a regular basis then the sounds can become more clear and strong. Professional singers usually build their careers around one specific musical genre, such as classical or rock, although there are singers with crossover success (singing in more than one genre). They typically take voice training provided by voice teachers or vocal coaches throughout their careers.
