About · the program

One program,
and it gets out of the way.

Arietto is a notation program for the Mac. It is meant to be picked up in an evening, to stay quick when the score gets big, and to give you pages you would hand to a player without fixing them first.

Where this comes from

The program I wanted for twenty years.

I spent twenty years writing and arranging on other people's software, and a great deal of those twenty years went into learning the software rather than writing the music: manuals, tutorials, forum threads, a private list of workarounds I had to keep in my head. More than once I stopped in the middle of a phrase to go and watch somebody explain how to enter a note, and the idea I had been holding was not there when I came back.

Arietto is the program I wanted during those years. Every decision in it answers one question: does this give the time back to the music?

I am a musician and teacher in Upper Austria, and I prepare parts for ensembles that rehearse every week. Arietto is made by Kammerwerk Technologies, the small company I founded to build it.

One mode.

You write, lay out and listen in the same window. You are always in the score, and what you learn once works everywhere.

Learned in an evening.

What you reach for most is where you would expect it, the defaults are the ones a working copyist would choose, and the first score you make should be one you are willing to hand out.

Engraving you do not have to correct.

Spacing, beams, slurs, accidentals and page turns are set as you write. Arietto makes the first proposal. You have the last word, and what you move stays where you put it.

Quick on a big score.

Written in Rust and drawn on the graphics card, so a full orchestral score stays quick to work in, late in the evening, on an ordinary laptop.

Score, parts and sound

From two players to a full orchestra.

Parts come out of the score and stay in step with it. Sampled instruments and a mixer are part of the program, with nothing further to buy.

The closed beta opens this autumn for macOS. It is small on purpose, and every application is read by the person who built the program.
