Andrew Lloyd Webber is donating more than £380,000 to arts education projects across the UK, through his philanthropic foundation.
The Royal Ballet School will receive £180,000 to support young people from disadvantaged backgrounds.
A £75,000 grant will go to Creative & Cultural Skills to train technical theatre staff.
The Foundation is dedicated to supporting a new generation of people entering the arts.
Foundation trustee Madeleine Lloyd Webber, the wife of Lord Lloyd-Webber, said: "The Foundation is delighted to be able to support such a diverse range of arts education initiatives as we feel it is hugely important to encourage the next generation of artistic talent.
"The UK is currently a global leader in the arts, and by investing in programmes to train young artists, we hope our country can continue to be a creative force."
Other recipients include the Wales Millennium Centre's Creative Apprenticeship Scheme, which will receive £45,000 over three years to train backstage staff.
The grant will fund a full-time apprentice in their studies and training.
A £20,000 grant will go to Live Music Now, a project founded by the late violinist Yehudi Menuhin, to fund a two year programme to train and support 20 of the best emerging musicians to deliver workshops to children with special educational needs.
Finally, a £10,000 one off grant has been allocated to the Old Vic New Voices (OVNV ) Programme at The Old Vic theatre in London.
The programme helps develop the careers of emerging actors, directors, and producers under the age of 25, working alongside mentors who have included artistic director Kevin Spacey.
