Harmonium is a composition for chorus and orchestra by the American composer John Adams, written in 1980–1981 for the first season of Davies Symphony Hall in San Francisco, California. The work is based on poetry by John Donne and Emily Dickinson and is regarded as one of the key compositions of Adams' "minimalist" period.

The work was premiered by the San Francisco Symphony and San Francisco Symphony Chorus, with conductor Edo de Waart, on 15 April 1981, and subsequently recorded it. The UK premiere was on 13 October 1987 at Birmingham Town Hall, with the City of Birmingham Symphony Orchestra (CBSO) conducted by Simon Rattle. Rattle and the CBSO gave the London premiere on 28 July 1990 at The Proms.

The Purcell School for Young Musicians is a specialist private music school for children, located in the town of Bushey, south Hertfordshire, England, and is the oldest specialist music school in the UK. The school was awarded the UNESCO Mozart Medal in 2003, which was received on behalf of the school by King Charles, who is a patron of the school. Sir Simon Rattle is honorary president of the school. Many of the pupils subsequently study at leading conservatories across the country. In 2015, the School became the first Fazioli Pianoforti Centre of Excellence.

The School's pupils are funded largely by the Government's Music and Dance Scheme, along with the School's own scholarship funds. It has a consistent success in national and international competitions and has an extensive programme of outreach and community work. The majority of pupils progress to music conservatoires although a small number each year elect to go to University to study both music and non-musical subjects.
