The tuner shows exactly where you are. Your accuracy gets a little tighter every session. A structured Star Map curriculum. No guessing what to practice. The Star Map lays out everything you need to learn, one topic at a time. Finish one, unlock the next. Always know what you've completed and what's ahead. Beautiful design built for daily practice. Five minutes a day, pretty enough to actually open. No clunky interface, no intimidating textbook layout. Just clean exercises that make practicing feel good. WHAT YOU'LL PRACTICE Pitch matching. Start matching simple notes from day one. Build up to finer differences. Watch your accuracy climb session by session. Solfege and relative pitch. Learn to hear the relationships between notes by singing solfege syllables. Start with simple patterns, work up to recognizing any note's role in a key. Intervals. Begin with the easy ones, the ones your ear already knows from songs. New intervals layer in as the basics click. Before long you're recognizing them in real music without thinking. Harmony. A chord plays. You identify the quality. Major? Minor? Something spicier? It starts simple and builds. Rhythm. Listen to a pattern, clap it back. As your timing locks in, the patterns get more interesting.
