About MusiCompanion

• A tuner that speaks the language of early music: every pitch from 380 to 460 Hz and the historical temperaments (Vallotti, Kirnberger III, Werckmeister III, Bach-Kellner, Young, meantone…), with their reference key.
• My instruments and my temperaments: up to 15 instruments saved with their pitch and temperament, and up to 15 personal temperaments set note by note.
• The historical winds assistant: play a few notes, and the app determines the pitch and natural temperament of your historical wind instrument.
• Truly in-tune drones: a real recorded piano and an organ, retuned to the chosen pitch and temperament, short or sustained, to work on the intonation of intervals and on ear training.
• A practice log to share: practice-session stopwatch recorded automatically in the calendar, comments dictated by voice, audio recordings, and sending your work to your teacher by e-mail or WhatsApp.
• To understand what you play: the main rhythmic cells (from 2/4 to 12/8) played with the beat, with tests, composers from the Renaissance to the 20th century, and ornament tables of the 17th and 18th centuries with their original treatise.

MusiCompanion is a tool to put in your child’s hands to encourage regular practice: they see their sessions add up day after day, record and listen to themselves, and can send their work to their teacher.

An old phone, even without a SIM card or a plan, works very well: you only need a Wi-Fi connection when installing it.

An Internet connection (Wi-Fi is enough) is needed only once, to open the app and install it on the home screen. It is then stored entirely on the device and works offline afterwards.

Without Internet, everything essential works: tuner, metronome, drones and sounds, rhythms and keys, composers, my instruments, stopwatch, calendar, written comments, recordings and backups. Once activated, the Complete version stays active offline.

An Internet connection is needed to:

• install the app and receive updates (they arrive at the next connection);
• sign in to your account, buy or manage a subscription;
• send your work by e-mail or WhatsApp (an e-mail prepared offline is sent at the next connection);
• dictate comments: on most phones, dictation goes through the Internet (you can always type them);
• open the “Sources” links on the composer pages.

For a device that stays offline, saving a backup file (Settings › Backups) lets you transfer the work to another device, for example with a cable.

• Android: Android 8 or newer, with an up-to-date Chrome browser (version 111 or later). Since Chrome 139, Chrome updates require Android 10 or later.
• iPhone and iPad: iPhone 8, iPhone X, iPhone SE (2nd generation) or newer, with iOS 16.2 or later.
• Processor and memory: a quad-core processor and 2 GB of RAM are enough (most phones sold since 2018). On a slower device, the tuner may react a little more slowly.
• A working microphone (tuner, recordings) and a speaker or headphones (metronome, drones).

On an older device, the app may open, but some colours, the microphone or the sounds may not work properly.
