Musical notation has been readable for roughly a thousand years. It has, until now, never been reliably hearable by rolling a cursor across it. We identified this gap ourselves, without being asked, and closed it. You are welcome.
Every notehead on the grid corresponds to a specific pitch, generated on demand via sine wave the instant your cursor — or, for the unequipped, your finger — arrives above it. Each tone lasts under half a second. This is intentional. We do not linger.
Every distinct pitch you personally trigger counts toward your Audibilization Coverage. At 100%, you will be shown a small banner confirming as much. There is no prize, download, or further content behind it. The banner is the entire reward, and we stand by that decision.
Some symbols on the grid are rests — silences, by definition, in standard notation. Hovering one produces no pitch, because a rest has no pitch. We do, however, play a brief breathy sound and log the encounter, so that your cursor's effort is not entirely wasted. Nothing happened. That was, notation-wise, the correct outcome.
It probably doesn't, in any measurable sense. But somewhere around the eighth or ninth note, you may have started listening for the next one before your cursor arrived. That anticipation is the entire initiative. Everything else is certification paperwork.
