Ho's major interest is in developing and promoting the art of harmonica quintet playing.  He founded the King's Harmonica Quintet in 1987 and thus created a revolutionary form of harmonica performance.  His innovative musical rearrangement for the quintet, as well as his outstanding harmonica technique, has given him remarkable acclaims.

Since the formation of the Quintet, Ho has appeared on concert stage for numerous times both locally and internationally, including Japan, the United States, Germany, Malaysia and Taiwan.  In the 1995 World Harmonica Championships in Japan, Ho swept the board in the categories of duo (champion), trio (the second runner-up) and group of 4-6 persons (the first runner-up). In the 1997 World Harmonica Festival in Germany, his outstanding musical talent secured him a number of awards in the competition: champion in the group of 4-11 persons category, first runner-up in the open category, partnering with Chan Shu-keung, Kenneth, and second runner-up in the chromatic solo category.

Subsequently, he was honored to be invited as the adjudicator and guest performer for the First and Second Asia Pacific Harmonica Festival and Competition held in Taipei and Kuala Lumpur in October 1996 and August 1998 respectively.  He also conducted seminars on the skill of chromatic harmonica playing and the art of harmonica quintet performance for  both amateur and professional harmonica players from various Asian countries.   In the Malaysia national harmonica competition held in December 1997, he was once again the adjudicator as well as the one of the top Asian harmonica players to perform in the gala concert.

Chan, together with Lok Ying-kei, Rocky, a member of the King's Harmonica Quintet, was the champion with distinction result in the duo category in the 1985 Schools' Music Festival.  Ten years later, they partnered again in the 1995 World Harmonica Championships.  This time, they became the world class first runner-up in the duo category.  In the 1997 World Harmonica Festival, Chan partnered with Ho Pak-cheong to play a duo and came second in the open category of the competition.  Apart from this, he was awarded the fourth place in the chromatic solo category.

Chan has been the second harmonica in the King's Harmonica Quintet since its establishment and has been regarded as the best candidate for serving this position because of his unique blending tone quality.

Lau's role as the third harmonica in the Quintet is pivotal to its remarkable ensemble effect.  He is one of the contributors to the repertoire of the Quintet by making arrangement of string quartet pieces for five harmonicas.  In the arranged score, he has to play the parts of violin, viola or cello to achieve the best musical effects. He has thus developed a high degree of sensitivity to such a dynamic role and a wide spectrum of musical expression and tone color. 

Lau strongly advocates the tenor harmonica being an essential member of the harmonica family which has both the blending power in group playing and the expressiveness of a solo instrument.  In the 1995 World Harmonica Championships, he transcribed the famous Andante cantabile from Tchaikovsky's String Quartet No.1 for a duo of tenor harmonica and bass harmonica and was awarded the sixth place.  In the 1997 World Harmonica Festival chromatic solo category competition, he played Tchaikovsky's Canzonetta from Violin Concerto with tenor harmonica.  The piece of music exploits the range and tone color of the tenor harmonica and was awarded the fifth place.

With his information technology background, he contributes to the publicity of the Quintet by setting up a website for the Quintet on the Internet at his leisure.

During the period from 1987 to 1989, Lok virtually suspended all his harmonica activities when he concentrated on his career.  In 1991, he joined the King's Harmonica Quintet when the tenor player Dr. Poon Chung Keung left for pursuing his doctorate study.  Since then, Lok resumed his enthusiasm in harmonica and classical music activities.

In the 1995 World Harmonica Championships, Lok did virtually most parts that he could in various categories of the competition.  He was awarded the sixth place in the solo (chromatic harmonica) category, the first runner-up in the duo category, the second runner-up in trio category where he played the bass part, and the first runner-up in the group of 4-6 persons category.  In the 1997 World Harmonica Festival, Lok again entered in most categories of the competition.  Results were awards of excellence on top of being a member of the Champion Quintet.

In July 1999, Lok was featured as the only overseas guest performer in the annual convention of the Woodstock Harmonica Association of Sydney, Australia.  The audience was deeply impressed by his recital comprising more than half an hour of classical harmonica music.

With his experience in harmonicas of various ranges (treble, tenor and bass), Lok aims to explore the expressiveness of a tenor harmonica through combining various techniques on different harmonicas.

Kuan began his harmonica lesson in 1979.  Being an outstanding bass harmonica player, he was the best candidate for the seat of bass harmonica when the world-renowned King's Harmonica Quintet was established.  The repertoire of the Quintet, which consists mostly of string quartets, demands exceptional skills of the bass player.  Kuan succeeded in overcoming the technical hurdle, while at the same time contributing to the overall musicality of the Quintet.  His playing has astonished professional and amateur harmonica players as well as audiences from all over the world.  "The bass playing is outstandingly sensitive, it doesn't sound like a bass harmonica being played!", exclaimed Douglas Tate, the British harmonica legend.  Yasuharu Mano, President of Japan's Tombo Musical Instrument Co. Ltd., also described him as the "best bass harmonica player".

In the 1995 World Harmonica Championships, he won many awards in different categories including: first runner-up in the group of 4-6 persons, second runner-up in the trio category, the fifth place in the category for the future and the sixth place in the duo.  In the 1997 World Harmonica Festival, his bass harmonica again earned him the fifth place in the open category of the competition and champion in the group of 4-11 persons category.

Since then, Kuan with members of the King's Harmonica Quintet appears often in Asia-Pacific Harmonica Festivals as adjudicator, guest performer and guest speaker.
