EarMaster is a music application for Windows, Mac, iOS and Android launched in 1996 by Danish editor Miditec, who changed its name to EarMaster ApS in 2005. The first prototype version of the software was DOS-based, but since 1996, it has been ported to multiple operating system. The main focus of EarMaster is ear training and sight-singing, even though EarMaster seems to tend towards a more general approach to music teaching since v. 4.0, covering a broader spectrum of music theory and practice.
