Gurlingo is an app developed through the Gurmat Sangeet Research Internship, designed to help users strengthen their understanding of two fundamental concepts in Gurmat Sangeet: Sur (musical notes) and Raag (melodic frameworks). Gurlingo will be available for free on Apple App Store and Google Play Store. The first release has three main features: a Scale Selection feature, Sur Training, and Raag Training. The Scale Selection feature allows users to customize their learning experience by choosing their preferred scale: G# or C#. The Sur Training learning track focuses on ear training and sur identification through quizzes with practice exercises. The Raag Training learning track introduces a basic overview of the 31 Shudh Raags from Sri Guru Granth Sahib Ji, and progresses to focused training on 10 select raags: Bilaval, Gond, Basant, Kalyan, Maru, Shree, Todi, Sarang, Malhar, and Bhairo.
