Glozzer is a singing-technique notebook, made for people who love to sing and want to nail a song line by line. Paste in your lyrics and mark how to sing every word — drop in purpose-built symbols for accent, breath, resonance, articulation, and more with a single tap. ■ Key features ・Mark right on the lyrics: purpose-built symbols for accent, breath, resonance, glissando, articulation and more, aligned precisely to each word. ・Organize in layers: your teacher's directions and your own practice notes each get their own layer — show or hide them, so nothing gets in the way. ・Workspaces and folders: sort different songs and different stages of progress into their own place. ・Practice notes and warm-ups: jot down what mattered in each session, your warm-up routine, and your range. ・Share in one tap: copy the parts you choose into a brand-new workspace to share with a student or friend — the two stay separate, so neither affects the other. ・Start as a guest: no sign-up needed; when you want to keep your work across devices, sign in with Google or Apple. ■ Who it's for ・Anyone learning to sing: keep every line's technique cues on the lyrics, so they're clear the moment you practice. ・Singing teachers and classes: turn spoken guidance into marks students can actually read and take home to practice. ・Self-taught singers: capture the techniques you pick up and your own insights, all on the song itself. ■ Your content, your call The text you paste and the marks you make are stored safely in your account, ready to pick up across devices. This is your private content: we don't provide a lyrics database, we don't source lyrics from third parties, and we never make your content public or share it — and you can delete it anytime.
