Harriet Adie

A busy professional harpist for over 15 years, Harriet Adie is known for her intense musicality, creativity, and focus. Harriet is passionate about her instrument and enjoys the many opportunities her performing career has provided for sharing her love of the harp with other people.


Harriet’s introduction to the harp was far from conventional: she first began lessons in Oman in the Middle East, where fishing wire proved a suitable replacement for any broken harp strings! 3000 miles later, she was awarded a place at the Junior Department of the Royal College of Music under the tuition of Daphne Boden. This was followed by reading Music at Balliol College, Oxford where she was an Instrumental Exhibitioner. Harriet then completed her studies with Imogen Barford at Trinity Laban Conservatoire, supported by awards from the Musician’s Benevolent Fund, the Countess of Munster Musical Trust, and the Martin Musical Scholarship Fund.


An accomplished chamber musician, Harriet has performed with renowned ‘cellist Julian Lloyd-Webber, and was for many years, a member of the Swan Duo with ‘cellist Jessica Burroughs.   Harriet is a founding member of the internationally recognized ensemble 4 Girls 4 Harps, whose music has been broadcast on Classic FM, BBC Radio 2, BBC Radio 3 and BBC Radio 4, as well as across the world as far as Australia and the USA.


As a soloist she has given many recitals at major London venues including St Martin’s-in-the-Fields, the National gallery and St James’s Palace. Her most recent solo recording of music by Carey Blyton received 3 stars from BBC Music Magazine, and her performance was described by MusicWeb International as ‘…could not be bettered. The young harpist Harriet Adie plays with character and total understanding.’ Harriet has also enjoyed working with many orchestras including the Philharmonia Orchestra (where she also performed in their Music Of Today series), the Orchestra of the Swan, London Festival Sinfonia, Covent Garden Sinfonia, and Northern Sinfonia.


Alongside her career as a professional harpist, Harriet is also a composer specializing in solo and chamber works for harp.

She gives workshops throughout the UK on the functionality of the voice, accent breathing and vocal care and maintenance. She gives workshops and courses on voice science, tips and techniques for choral singers, maintaining the mature voice and breathing. She is an adjudicator for the International and British Federation of Music Festivals.

Rebecca has an MA in musicology and is currently nearing the end of her PhD research at UCL. Her research investigates what interventions can maintain the functionality of the mature female voice. Findings from this study are statistically significant and support the hypotheses that the vocal competency of the mature female singer can be sustained through effective pedagogy. This is leading to her current work on devising a new teaching method specifically for the mature voice and choral singers. The first presentation of this work was at the Pan European Voice Conference in Copenhagen in August 2019. In 2022 she presented at ICVT in Vienna and the Pan European Voice Conference in Tallinn

Her PhD will be complete in 2023 and she will publish a book on effective teaching methods for the mature voice and already has an agreement with a publishing company.
