Pippa Macmillan is a renowned specialist of historical bass instruments. The first graduate of the Royal Academy of Music to major in baroque bass, she has since completed a Masters in Historical Performance at The Juilliard School, New York City, and is now Professor of Baroque Bass at the Royal College of Music. She studied with Chi-chi Nwanoku, Robert Nairn and Sarah Cunningham (viola da gamba).

Pippa was a member of the Monteverdi Apprenticeship Scheme 2012/13 under Sir John Eliot Gardiner, and performed with the English Baroque Soloists and Orchestre Révolutionnaire et Romantique at the BBC Proms, Carnegie Hall, and Leipzig Bach Festival.

On modern bass, Pippa is Principal Bass with the Orchestra of St Paul's, Covent Garden.

In her teenage years, Pippa was a member of the National Youth Orchestra of Great Britain for five years, and principal double bass for three of those, leading to opportunities to perform in every major concert hall in the UK. She toured three times with the European Union Youth Orchestra, including as principal double bass, performing all over Europe and in Kazakhstan. Pippa was a member of the 2011 European Union Baroque Orchestra, and underwent a series of five tours with the orchestra as well as performing at the Edinburgh International and Lufthansa Baroque Festivals.
