The musical foundation of Chichester Cathedral consists of the organist and master of the choristers, the assistant organist and the organ scholar; together with six singing men (called lay vicars), eighteen choristers, six probationers – and including a head chorister and a senior chorister (deputy head) who both wear a notable medallion on a red ribbon according to their office held. The choristers and probationers are all boarders at the Prebendal School, the cathedral's choir school. The lay vicars are professional singers who all have everyday jobs. During school term, the cathedral has eight sung services a week. As well as singing, choristers learn the piano and an orchestral instrument, spending at least eighteen hours a week on musical performance.
