Terence Lam Ka-him (Chinese: 林家謙; born 3 September 1991) is a Hong Kong composer, singer-songwriter, and record producer.

Lam has composed songs for the singers Eason Chan, Jason Chan, Hins Cheung, Pakho Chau, JW, Charmaine Fong, Alfred Hui, Eman Lam, Janice Vidal, Rainie Yang, and Joey Yung.

Lam's composition of the JW song "A Lifetime of Contradictions" (Chinese: 矛盾一生) was the first to receive widespread attention.

[2][5] Lam attended St Joseph's College, a Catholic boys' secondary school in Hong Kong.

[3] He is also an alumnus of Hong Kong Sze Yap Commercial and Industrial Association Wong Tai Shan Memorial College [zh], where he completed his sixth form studies.

[2] Lam graduated in 2013 from Lingnan University, where he received an honours Bachelor of Arts degree in Contemporary English studies.

[11] The singer Pakho Chau's 2014 song "About Us" (Chinese: 關於我們) was the first of Lam's compositions to achieve commercial success.

[13] JW's singing of "A Lifetime of Contradiction", which received over 18 million views, revitalised her previously flagging career.

[10] He has written songs for the singers Charmaine Fong,[10] Pakho Chau,[10] JW,[10] Alfred Hui,[10] Jason Chan,[10] Joey Yung, Hins Cheung,[10] Janice Vidal,[10] and Eman Lam.

[13] Lam composed Joey Yung's song "The Science of Heart" (Chinese: 心之科學), which received an Ultimate 903 award in 2018.

[18] The song's music video features four new actors including Rachel Leung and Will Or to accompany Lam in acting various scenes of people being in a "collapsed state".

[18] Lam composed fewer songs in 2019 than he did in previous years as he was adjusting to becoming a performer and as his energies were focused on promoting his work and planning.

[10] In 2020, he released a favourably reviewed song titled "In a Funk" (Chinese: 拼命無恙), which detailed a love rectangle.

[13] The song's lyrics expounded on the loneliness common in life and came at a particularly timely moment during the COVID-19 pandemic when people were social distancing.

[21] Writing in The Loop, music critic Yannie Chan said "Solitude" "features an addictive melody and meaningful lyrics celebrating the art of enjoying time by yourself".

[24] His decision was because he didn't want additional copies to make his work sell poorly and as a result have to be sold at a discount.

[25] One website offered to sell both versions of Lam's EP at HKD$2,800 (US$360.36), which was a tenfold increase from the original price.

[25] Lam initially had reservations about making the EP as he was uncertain about whether people would still buy physical copies of albums.

[24][26] After he heard from his fans that his songs had many common characteristics, he within a month took his five most recent compositions, added his demo cover of "Solitude", and composed some simple music to connect them together to create the EP.

[24] SPILL music critic Fan Wong found that "the songs were all high quality but they were inevitably lacking in freshness" since they had previously been released.

[27] His songs "Listen to Wind" and "In a Funk" made Wong think of the sophisti-pop genre in making people ponder and have feelings of refinement.

[28] An HK01 music critic said that while Lam's previous songs largely had a pessimistic theme, "Terence's Adventures in Wonderland" is "a breakthrough" in being different and "proves that he can cater to the market and to the public while insisting on his own style".

[28] Lam performed a live in-studio duet of the song "Quarantine" (Chinese: 隔離) with Jace Chan.

[32] In contrast to most of the other male attendees who wore suits, Lam wore a less formal Mike Amiri "multicolour souvenir patchwork hoodie" and a Paul Smith shirt with colourful striped patterns to match his performance that night of his song "Terence's Adventures in Wonderland", to make it easier to play the guitar, and to make himself more comfortable and relaxed.

[13] Owing to the COVID-19 pandemic, Lam had a lower income and fewer performing opportunities so he had more time to compose songs.

[36] In April 2021, he rewrote the lyrics of Lam's most recent song, "The Magical Confused Potion" (Chinese: 神奇的糊塗魔藥).

[38] His behaviour at the award ceremony led critics to call him "arrogant" and "disrespectful", and to question why he became a singer instead of remaining a behind-the-scenes composer.

[38] A day after the awards ceremony, he released a statement thanking ViuTV and his fans, saying "there is a lot of room for learning and improvement in expressing myself".

[12] K Law of U Lifestyle found that Lam had "special timbre, an introverted singing voice, and was good at transcribing the songs with varying degrees of play".

The critic concluded that "the combination of Lam's elegant singing and his traditional yet embellished with the unconventional performance makes him so memorable".
