THE pipes are calling . . . and so are the mandolins, guitars, fiddles and flutes.About 150 people have heeded the call of the Lake School of Celtic Music, Song and Dance which began yesterday in Koroit for its 10th year.The week-long event teaches people of all ages everything from uilleann pipes and tin whistles to songwriting and bodhran (Irish drum).Event director Felix Meagher said there were about 150 students in town for the week of classes and concerts."The town has really embraced the Lake School," Meagher said yesterday.Participants will come from as far afield as Darwin this year and there's "normally a good spread of people from Geelong, Melbourne, Adelaide and Sydney," he said.For its 10th birthday, the Lake School had broadened its focus, Meagher explained."We've tended over the years to concentrate on beginners but now we're also concentrating on experienced players."We've got a master class on Irish music being taught by Danny Bourke on Friday, whose grandfather was a previous mayor of Koroit."Other tutors involved include Ted Egan, Paddy Fitzgerald, Ewen Baker, Vince Brophy, Maria Forde, Tommy Carty and Dennis O'Keeffe.
