Daily Ear Training

Daily Ear Training is the date-stable version of the Ear Training specialist. Each date produces a reproducible twelve-round mixed interval session, and the result is stored locally without changing the platform's existing Today’s 6 rotation.

How the daily session is chosen

The date is converted into a deterministic seed. That seed controls the permitted interval classes, root pitches and playback order, so revisiting the same date recreates the same underlying exercise. There is no server-side content feed and no external audio request.

Six-day difficulty rhythm

The daily schedule intentionally varies difficulty rather than making every day identical. Easy appears twice in each six-day rhythm, Standard three times and Challenge once. Every Daily session still uses twelve questions, which keeps a streak day comparable in length even when the answer pool changes.

Why the session mixes playback types

Daily uses ascending melodic, descending melodic and harmonic presentations instead of specializing in only one. The three types repeat through the twelve rounds, so the daily check-in samples multiple ways the same interval knowledge can be heard.

Clean and Assisted records

Replay does not make a session Assisted. Listening again is part of ordinary ear practice. Using Hint does mark the record Assisted because Hint reveals the semitone distance. Local history therefore separates a fully self-identified run from one completed with explicit answer information.

Local streak behavior

When a Daily session is completed, the browser stores the date, score, time, replay count and Clean or Assisted status. Consecutive completed dates build the specialist streak. Returning to the same completed date restores its completion state rather than creating a second streak credit.

Audio is synthesized, not streamed

Each pitch comes from a Web Audio oscillator using equal-tempered frequency calculations. The exercise does not contain recordings of songs, instrument samples or third-party audio packs. This keeps the activity local-first and makes the prompt generation independently reproducible.

Daily versus Today’s 6

Daily Ear Training is intentionally separate from Today’s 6. Adding a new specialist should not silently change the frozen 2026 core rotation. You can use Daily Ear Training as an optional extra without altering the established six-game daily set.

Accessible controls

Answer choices are real buttons that work with pointer, touch and keyboard focus. Number keys can choose visible answers and Space can replay the current interval. The status region reports whether the previous answer was correct and names the expected interval.

What is measured

The game records actual session facts: correct answers, total questions, elapsed time, replay count and hints. It does not translate those facts into an IQ score, hearing age, medical label or fabricated percentile.

When to use Practice instead

Use regular Practice when you want to repeat one difficulty or isolate ascending, descending or harmonic recognition. Daily is better when you want a small date-stable routine that changes automatically without selecting options each time.

Use the correction, not just the score

After each response, the game names the correct interval before the next round begins. That immediate correction matters more than chasing a perfect percentage: it lets you compare the sound you expected with the sound that was actually generated. Replaying the prompt after a miss can help you notice whether you confused neighboring intervals, direction, or the difference between melodic and harmonic presentation.

Keep volume comfortable

Daily Ear Training is designed for ordinary speakers or headphones at a comfortable level. Louder is not better. The exercise does not estimate a hearing threshold, and it does not need microphone access. If a device distorts low or high tones, switch output devices or lower the volume rather than treating a difficult prompt as a personal ability score.
