Original: Purcell also had a strong influence on the composers of the English musical renaissance of the early twentieth century, most notably Benjamin Britten, who created and performed a realisation of Dido and Aeneas and whose The Young Person's Guide to the Orchestra is based on a theme from Purcell's Abdelazar.
Simplified: Benjamin Britten wrote a piece called The Young Person's Guide to the Orchestra which is based on a tune from Purcell's Abdelazar.
