No named expert review is claimed for this release.
What the data covers
The current release covers standard Boehm-system B♭ soprano clarinet, written E3–C6: 33 chromatic pitches and 39 basic fingering options. Sharp and flat spellings can share one pitch record.
Written pitch is used for lookup and staff notation. Concert pitch is a whole step lower and is used for the synthetic reference tone. Written C4 therefore corresponds to concert B♭3.
This release does not cover bass clarinet, other key systems, extended-key mechanisms, notes above C6, or passage-specific trill, resonance and intonation fingerings.
Open the fingering chartHow sources are compared
Each released basic option records references to Yamaha’s Boehm clarinet guide and the Woodwind Fingering Guide. Records include the relevant URL and source location. Multiple pages from the same publisher do not count as independent sources.
Source cross-checked means the option meets the release’s source-agreement and key-state requirements for the standard Boehm profile. It does not mean the source publishers endorse Happy Clarinet or that a named professional has approved the full dataset.
When a basic state cannot be supported confidently, the correction process calls for investigation or withholding the option rather than filling in the state by analogy.
What a review checks
1. Compare references
Compare the recorded basic fingering and its scope across independent references. Keep a source location for each released note.
2. Validate finger and key states
Check the thumb hole, register key, six main holes and named additional keys separately. Check written pitch, concert pitch and spelling against the same pitch record.
3. Check screen and print
Check that the selected-note label, notation, diagram, instructions and tone agree. Check keyboard behavior and narrow layouts, then check the full chart on both supported paper sizes.
E3, F3, F♯3, B4, C5 and C♯5 retain two equal basic little-finger options. The chart shows both and asks the player to use one, not both. These checks assess data and implementation; they do not assess a player’s performance.
See the basic alternativesHow diagrams and PDFs stay aligned
Happy Clarinet renders original schematic diagrams from structured finger and key states. The screen, written instructions and printable chart use the same released records. Additional keys are named without guessing their position on every instrument.
The print layout contains all 33 notes across four pages, including both little-finger options where applicable. Staff notation uses flats; text labels include available sharp and flat spellings.
Download the ready-made US Letter or A4 PDF, or choose a paper size and use Print / Save PDF. The downloadable files are generated from the same print layout, and an automated check fails if the data, diagrams or print styles change without regenerating them.
Open the print layoutVersions and corrections
The dataset version and source-check date identify the data release. A page update date describes a content change. Neither date is reset automatically on each build or visit.
A correction starts with an exact written note, instrument system, observed issue and supporting evidence. The review distinguishes a basic-data error from a rendering or pitch-label error and from a context-specific alternative outside this release. A confirmed change must go through the applicable data, screen and print checks before replacing the public record.
