The Hallelujah Chamber Orchestra (HCO) was formed in January 2019 under the auspices of Hallelujah Oratorio Society (HOS). Being a part of HOS, HCO aligns with the mission of “Promoting Church Music to Glorify God and Edify Man” and aims to hone musicians in the aspects of musical excellence and spiritual growth. HCO began with a dozen string musicians, led by founding director Mr. Peter Yan, playing under the baton of music director John Tong. In 2021, Kimberlyn Wu joined in as a concertmaster and violin instructor.

The group aims to develop into a full orchestra that can play an active role in HOS performances and ministry programs. HCO currently runs a music program comprising a Violin Program (for beginners), Junior Orchestra (for Grade 3 & 4) and HCO (for Grade 5 & above) and is actively recruiting new members.

The recent concert in Dec 2021 saw HCO performing Bach’s Orchestral Suite No. 3, Violin Concerto in A minor and Mozart’s Exultate Jubilate and Symphony No. 40. Works performed in past concerts include Mendelssohn’s String Symphony no. 10, Mozart’s Divertimento in D major K136, orchestra arrangements to Christian hymns and the Christmas Canticles, a choral suite composed by Benjamin Harlan. The young team has also performed in several casual settings and a worship service, having also taken part in a masterclass with Wu Man Yun, from the SSO violin section.

哈利路亚室内管弦乐团，附属哈利路亚圣乐社，于2019年一月分正式成立，以圣乐社宗旨“促进圣乐，荣神益人”为导向，专注在技巧以及灵命方面培育基督徒乐手，朝向卓越。在一年之间，乐团十多位年轻的弦乐手由创办主任颜彼得先生以及音乐总监张桐老师带领；2021年，余佩诗老师加入行列，担任助理弦乐导师。

乐团当前的目标是要装备更多乐手，发展成为一个完整的室内管弦乐团，参与圣乐社的音乐会以及事工活动。乐团按程度的不同分别进行新团员招募与训练，这包括小提琴基础训练、少年管弦乐团以及哈利路亚室内管弦乐团。

2021年，乐团演出的作品有巴赫管弦乐第三组曲、莫扎特Exultate Jubilate与第40管弦乐交响曲。其他近期演出的作品包括孟德尔颂的第十弦乐交响乐、莫扎特的《D大调嬉游曲》K136、基督教诗歌弦乐版以及Benjamin Harlan创作的《圣诞颂歌》组曲。除了公开音乐会演出，这年轻的乐团也参与圣乐的服事，例如圣乐主日崇拜以及一些聚会中演奏，并参加由新加坡交响乐团小提琴手，吴漫云女士，所带领的弦乐大师班。
