Altarab — a complete Arabic music academy on your device. الطرب 12 tools, built around the maqam tradition and quarter-tone tuning that defines Arabic music. Designed for oud players, ney players, qanun players, vocalists, and anyone learning Arabic music theory in earnest. TOOLS • Tuner — cent-accurate microtonal tuner with the 24-TET grid that Arabic music actually uses (Yegah, Rast, Sikah, Awj, etc.). Includes a pitch-pipe reference tone for tuning by ear. • Metronome — sample-accurate AudioContext scheduler, seven time signatures (2/4 through 9/8), and a tap-tempo button. • Iqaa — a percussion lab with eight Arabic drums (darbuka, riq, tabla, duff, khashaba, sagat, bendir, davul). Pick a drum, pick a rhythm from the 43-cycle library, watch it play. • Iqaa Trainer — tap-along scoring for those 43 rhythmic cycles, with tempo-ramp mode that lifts your BPM as you nail the cycle and a build-your-own-iqaa builder. • Maqam Explorer — all 73 maqamat with structure, branches, modulation paths, and a custom-maqam builder. • Maqam Comparison — side-by-side intervals and tuning comparison between any two maqamat. • Solfege — sight-singing exercises with quarter-tone awareness. • Oud Simulator — Iraqi-floating-bridge oud with maqam-aware fingering and Karplus-Strong physical modeling. • Scores — sheet-music library with synchronized OSMD playback, transpose, and loop. • Composer — 32-step grid with maqam-aware engine, MusicXML export, on-device • Songs — bundled Arabic MIDI library with piano-roll playback. • Karaoke — stem-separated mix-along for selected Arabic repertoire. • Follow Me — play-along trainer with synchronized score and audio, tempo 0.5×–1.5×. OFFLINE-FIRST Every purchased tool keeps working with no internet connection. Sample data ships inside the app, and entitlements live on your device. ONE-TIME UNLOCKS Each tool is a one-time unlock. The Tuner and the Metronome are free forever. Other tools include a 60-second preview so you can see what you're getting before you buy. QUARTER-TONE NATIVE Where Western music apps round to the nearest semitone, Altarab tracks pitches at one-cent precision and renders quarter-tone accidentals throughout — half-flats and half-sharps in scores, MusicXML export, and the Composer.
