Audio Sources: Acknowledgments and Gratitude

All the sounds — every quack, plink, and strum — come from the real thing. The audio has been edited, arranged, mapped and sequenced*, but it originates in the work of the people and projects below.

Instruments

Jabberblocky's melodies and generative music are played using recordings of individual notes from these instruments.

• Concert Grand Piano — the default piano in Jabberblocky — comes from the Salamander Grand Piano V3, recorded from a Yamaha C5 grand by Alexander Holm, licensed under CC BY 3.0.
• Felt Piano, the softer voice in the generative packs, comes from the VSCO 2 Community Edition Upright by Sam Gossner / Versilian Studios, released under CC0 1.0.
• The Nylon Guitar uses classical-guitar recordings from the Philharmonia Orchestra's sample library. The Concert Harp comes from the Versilian Community Sample Library (VCSL), also by Sam Gossner, under CC0 1.0.
• The Electric Guitar comes from FreePats, a project creating a free and open collection of digital instruments for music production. The recording is their FSBS Bridge Clean Electric Guitar, released under CC0 1.0.
• The cowbell, woodblock, castanets, spring coil, and squeaker used in the Frabjous sound pack also come from the Philharmonia Orchestra.
• The toy-piano samples are via Freesound contributors, "Toy Piano Samplepack" by poissonmort and "Michelsonne piano toy" by beskhu, both licensed under CC BY 4.0.
• The found-sound cork pops used in Frabjous were produced by Freesound contributors dr19 and lupums.

Music & scores

Jabberblocky's Musical Mode uses public-domain compositions. The playable score data behind each one was transcribed, arranged, or curated by someone, either working solo or as part of a larger effort, such as PDMX, a Large-Scale Public Domain MusicXML Dataset for Symbolic Music Processing. With gratitude:

• J. S. Bach's Cello Suite No. 1 — MIDI sequenced by David J. Grossman (jsbach.net)
• J. S. Bach's Toccata & Fugue in D Minor — transcription by hmscomp (MuseScore)
• Beethoven's Symphony No. 5, Finale — arranged for piano by the great Liszt, sourced from the PDMX open dataset
• Edvard Grieg's In the Hall of the Mountain King — via PDMX
• Mykola Leontovych's Carol of the Bells — arrangement by Xingyu Shui (aka pianofortemaster, MuseScore)
• Franz Liszt's La Campanella (MuseScore)
• Rimsky-Korsakov's Flight of the Bumblebee — transcription by james_brigham (MuseScore)
• Fernando Sor's Study in B Minor, Op. 35 No. 22 — sequenced by François Faucher (Classical Guitar MIDI Archives)
• Scarborough Fair (traditional) — via PDMX
• Gilbert & Sullivan's Major-General's Song — transcription by mls111888 (MuseScore)
• Bella Ciao (traditional) — transcription by PhivosK (MuseScore)
• Bunessan (traditional) — via PDMX

• Zequinha de Abreu's Tico-Tico no Fubá

*Depending on the source, recordings are selected, segmented, trimmed, faded, filtered, level-adjusted, normalized, layered, resampled, channel-converted, re-encoded, or mapped across pitches. Scores may be transcribed or extracted, reduced to playable notes and chords, transposed, phrase-mapped, and re-sequenced for interactive playback.
