Sweney’s mu­sic­al gift showed it­self at an ear­ly age. While still a boy, he be­gan to teach mu­sic in the pub­lic schools and lead Sun­day school per­form­ances. At age 19, he start­ed stu­dy­ing mu­sic in ear­nest un­der Pro­fess­or Bau­er, a cel­e­brat­ed Ger­man teach­er. He took vi­o­lin and pi­a­no les­sons, and about this time be­came a choir lead­er. He was al­so in con­stant de­mand for child­ren’s con­certs and for con­duct­ing glee clubs.
