EVI, Electronic Valve Instrument: A Simple Trumpet-like Tool

By Bartlomiej Niemtur

Open iTunes to buy and download apps.


Struck by inspiration but got nothing to play on? Ever wanted to practice fingerings, but couldn't?

Imagine what would it be to carry an instrument with you, ready to play anytime, anywhere. A tool that is practical, comfortable and fun.

Enter EVI app, an Electronic Valve Instrument, modeled after a real-world trumpet and adapted to your phone.

- Focuses on simplicity and usability
- Big buttons, play even without looking at the screen
- Valves placement and behaviour just like in the real trumpet
- Practical, play any trumpet note, anytime, anywhere
- Modern design, friendly interface, intuitive animations

EVI embraces the fact that it's not a real trumpet:

- Uses a simple, universal synth sound.

- No blowing into the microphone; use buttons instead. Three additional buttons correspond to blowing and embouchure changes, they're easy to reach and provide a more comfortable experience

Video available at: !

Carry an instrument in your pocket; practice trumpet fingerings or play, anytime anywhere. If you enjoy EVI, please remember to rate the app in the App Store!

Great for touring trumpet players!

This is a very interesting and useful app. You obviously can't do embouchure work with it, but the finger/note benefits are worth it. I can see myself writing, learning, and practicing horn parts without bothering anyone else in the van. Great app!


I've been looking for an app like this forever! It's a little tricky at first, but it's so awesome! Totally will recommend this app!


It works alright until you play a 2 valve fingering, which makes up for a lot of trumpet playing. Every time I try to play an A or E it says no more than 5 fingers at a time, even though I'm only using 3!
