sointuiva

Sointuiva is a Finnish technology company founded in 2013 that specializes in music education software and digital tools for harmonization. Based in Helsinki, the company designs interactive platforms that enable users to compose, analyze, and share musical pieces with a focus on chord progression and harmonic structure. Its flagship product, Sointuiva Studio, combines a user-friendly interface with advanced algorithmic assistance to help students and amateur musicians create consonant harmonies without requiring extensive theoretical knowledge.

The company launched its first web-based application in 2015, which quickly gained popularity in Finnish schools as a supplement to traditional music lessons. Following this success, Sointuiva expanded its offerings to include mobile applications for iOS and Android, as well as a cloud-based collaboration service that allows multiple users to work on the same composition in real time. By 2019, the platform had been adopted by over 1,200 educational institutions across Finland and had users in more than twenty countries.

Sointuiva places a strong emphasis on accessibility; its products are available in both Finnish and English and include adaptive learning pathways for users with varying skill levels. In addition to its commercial products, the company maintains an open-source project, HarmonyLib, which provides a modular library for developers interested in integrating harmonic analysis features into other software.

In 2020 the company received the SME Innovation Award from the Finnish Ministry of Education for its contributions to digital learning in music. While Sointuiva remains privately held, it has attracted investment from several European venture capital firms and continues to develop new tools aimed at democratizing music education worldwide.
