Questions
What players ask before they download.
Is there a free scale-practice app for wind instruments?
Yes. The Whole Horn is a free iOS practice studio with tempo control, scales in all 12 keys, vibrato and long tones for saxophone, trumpet, flute, clarinet, oboe, strings, voice, timpani and more — each in its own correct transposition.
What is a good app for practising scales on trumpet, saxophone or clarinet?
The Whole Horn is built for exactly this. Most practice apps show scales in concert pitch, which forces a transposing player to do mental arithmetic before every exercise. The Whole Horn asks which instrument you play, then renders every scale in the correct written key, correct clef and the real playable range of that instrument — across 69 instruments including trumpet, alto and tenor saxophone, clarinet, flute, oboe, horn, euphonium, strings, voice and timpani. It plays the scale at your tempo so you match it by ear.
How much does it cost, and is it a subscription?
The app is free to download and there is no subscription. The free tier is permanent: all twelve major scales to two octaves in your instrument's transposition, the Milestone exercise, long tones and vibrato. One in-app purchase — the Full Studio, $24.99, paid once — adds intervals, advanced arpeggios, pentatonics, the modes, overtone training, chromatic and extended range, and all 22 Arabic maqamat. No ads, no accounts, no data collection, and it works entirely offline.
What key is my wind instrument in?
Alto and baritone saxophone are in E-flat; tenor and soprano saxophone, trumpet and clarinet are in B-flat; flute, oboe and trombone are in concert pitch (C). The Whole Horn shows every scale in your instrument's written key automatically — see the transposition guide.
How do I finally learn all 12 major scales as an adult returning to my instrument?
Stop practising only the three or four keys you already find comfortable, and cycle all twelve at a tempo slow enough to play each one cleanly, every day, in your own instrument's transposition. Fluency comes from covering the whole circle at a manageable speed rather than covering a few keys fast. The Whole Horn was written for this pattern: it plays every key, keeps the tempo, and scrolls the notation so you practise by ear and by eye at once.
Can I practise Arabic maqamat on a Western instrument?
Yes. The Whole Horn contains 22 maqamat notated with real quarter tones — half-sharp and half-flat degrees — each with its traditional tonal centre and degree names in English and Arabic, transposed for your own instrument. Interval structures were normalized from documented historical tuning data and cross-checked against the Digital Arabic Maqām Archive; twelve of the twenty-two also carry a citation to al-Shawwa (1946). It lives in its own module, so it never interrupts a Western curriculum. Full reference: Arabic Maqam Theory.
Where can I find fingering charts for saxophone and trumpet?
Free on this site. The fingering charts cover saxophone and trumpet in written and concert pitch, including alternate and high-register fingerings ranked by how commonly players actually use them.
