Fixes for Intervals practice: bass clef notes now appear in the right place, every level asks the right kind of question and can be checked, and the Check button stays on screen on smaller laptops.

• Chords: build triads and seventh chords in every quality and inversion, explore the chords in any key, and see each one named four ways: words, chord symbols, roman numerals and figured bass. Five practice modes. • Intonation: train your ear with Sharp or Flat?, Fix the Chord Tone and Fix the Note, read the Just Intonation Chart, and see each note's tendency for your instrument on the tuner. • Arpeggio Fingerings: major and minor arpeggios on every band instrument, in your written key. • Scale & Key Explorer: scales, key signatures and the circle of fifths in one place, sized for your phone. • Eight new lessons for students in a class: Dynamics, Tempo, Articulation, Intonation, the Musical Alphabet and the Keyboard, Half and Whole Steps, Sharps, Flats and Naturals, and Enharmonic Equivalents.

Students can now sign in to their class, and every lesson has been rebuilt to fit the screen it is on. • Sign in to your class: students whose teacher uses CaesuraLab can sign in with a school Google account or an email address to see their classes, assignments and results. Signing in is optional. • Advanced Rhythms: new lessons on syncopation, cut time, triplets, compound meter in 6/8, 9/8 and 12/8 with duplets, and asymmetric meters. • Rebuilt lessons that fill the screen at any size, with a Contents list. • Rhythm Explorer: dotted eighths in every x/8 meter, dotted rests, and whole-measure rests in 2/4 and 3/4.

The largest update since 3.0: a new practice tool, rebuilt Tuner and Metronome, and a rhythm engine that counts the same way everywhere. NEW - Note Explorer. Browse the staff instead of being quizzed on it. Treble, bass and grand staff, with every note named and played. - Board Mode. Put the Tuner, Metronome or Rhythm Generator on a projector, with one control filling the screen for the room. - Dictionary. Every term on its own page, with search and a symbol beside each entry. REBUILT - Metronome. The beat comes first: a beat ring, tempo marking as a control, and time signatures one tap away. - Tuner. A larger meter face, a steadier needle, and two columns so the note and the cents reading are both legible from a music stand. - Rhythm Explorer. Custom time signatures, a bigger palette, tie and tuplet controls, and a staff that scales with the measure. RHYTHM AND COUNTING - Counting is now correct in 6/8, 9/8, 12/8, 5/8 and 7/8, including sixteenths and dotted values. - Rests hold their beats, and the counting says so. - Counting styles apply identically everywhere: traditional or Eastman, sub-counts above, below, in parentheses, or off. - Notation is drawn by one renderer throughout, so a beam, a clef, an accidental or a rest looks the same in a lesson, a quiz and on the board. ACCESSIBILITY - Every control has a name, a visible focus ring, and a target large enough to hit on a phone. - Text and interface colors meet WCAG AA contrast on every screen. FIXES - Saxophone and clarinet fingerings grade the key you actually press. - Every note a quiz can ask is a note the grader can read. - A custom rhythm selection that cannot generate a measure now says so.

Rhythm tools now cover every tuplet from duplets through septuplets, with one consistent note palette across all rhythm activities. Scale building accepts a correct scale in any octave. Fixes a header that shifted between tabs and a fourth quiz answer that could run off narrow screens.
