Herz Wind Orchestra 

桐蔭学園高等学校の卒業生によって結成されたOB及びOGのための吹奏楽団。名称は同校吹奏楽部の部是である「心の音楽」の理念を継承したもので、スローガンに「個のハーモニー」、モットーとして「心を掴む吹奏楽団」を掲げている。結成から1年を経た2023年2月には常任指揮者に作・編曲家で桐蔭学園高等学校吹奏楽部音楽監督の小野寺真氏を迎え、相模原市民会館にて第1回定期演奏会を開催。年1回の定期演奏会と室内楽演奏会を活動の軸としており、学年の壁を越えた信頼関係のなか、妥協なく吹奏楽の可能性に迫る。

A wind orchestra formed by graduates of Toin Gakuen High School for alumni and alumnae. The name is based on the philosophy of "music from the heart," which is the motto of the Toin Wind Orchestra(TWO), and the group's slogan is "Individual Harmony" and its motto is "a wind orchestra that captures the heart". In February 2023, one year after its formation, the band held its 1st  concert at Sagamihara Civic Hall with Makoto Onodera, composer/arranger and music director of the TWO, as the permanent conductor. The core of the group's activities is the annual regular concert and chamber concert, and the group pursues the potential of wind orchestra without compromise in a relationship of trust that transcends the boundaries of their grade.
