Sonid is a music education app that allows you to learn music theory in a fun and orderly manner.

It is different compared to other applications because it focuses on a single subject at a time. This approach will make your understanding of music expand more naturally and gives you the time to adapt to the new material. Complete Sonid and become a more refined musician.

Sonid is made for beginners and more advanced musicians that would like to broaden their musical horizon.

- Learn about a musical subject: a natural note, the perfect prime interval, the ionian major scale, a major seventh chord and many more.
- Answer questions about the subject you just learned about.
- Exercise a variety of topics. About notes, intervals, chords, scales and progressions. Change the difficulty of the questions you get: easy, intermediate, hard, expert or customized questions about topics you’ve learned.
- Unlock new modules to continue and expand your musical knowledge.
- Complete classes and lessons and earn experience points to buy badges and compete with your friends.
- Lookup detailed information about a musical term from anywhere inside the app.
- Display the notes from any scale/chord or interval in the playground.
- Get help at the in-app forum.

What can you learn?
For now Sonid focuses on harmony within music theory and ear-training. This means that when you complete all classes you will know how to:

- Build and play any existing scale, from major to minor and from lydian to mixolydian.
- Recognize keys and progressions within a key.
- You can read any chord symbol and understand which notes and intervals are in it and which scale it uses, like: Dmaj7#11 or G13.
- Recognize intervals, chords, scales and progressions by ear. (only if selected ear-training)

Why would you learn music theory?
- Help your ears to play the right note or chord by understanding which progressions are in a certain key. Or which scale is to be played at a given moment in your song.
- Make your playing sound unique by using different versions of chords, or replace them altogether to give a change of colour in your voicings.
- Composing new melodies and chord progressions will never feel the same after completing the music theory lessons. Explore new realms of music harmonies and take your listeners on a fantastical journey.
- Let your fellow musicians know what you expect from them using the correct terminology creating an open and creative environment to let your songs grow more naturally.
- Find the right notes at the right time. Play your solo with passion and rejoice.

Subscribe to Sonid Plus for even more content.
- Unlock exercises about various topics combined into tests. Like practicing a selection of easy intervals, or hard chords. Practice topics you've learned and continue on single topics you've completed.
- See statitics with the errors you've made giving you more insight in what you need to practice.
- Learn music theory without distractions from advertisements.

Really good! Although, one minor annoyance

This app is amazing for training you on music theory concepts. it’s very engaging and the content sticks pretty well! My one annoyance is the app can get pretty laggy and sometimes you’ll press a button several times thinking it didn’t register and then they’ll all happen at once after causing you to input the incorrect answer on accident. i think you shouldn’t be able to press submit if you haven’t answered the question yet.

Needs improvement

The lessons are keyboard based, but the keyboard is tiny and the app cannot be viewed horizontally.

I am on the major second section, and am asked to play two notes, but there is no sound when I play them. The explanation of major second is confusing. Why is it a major second between C and D, two semi-tones between, and also E and F, one semi-tone between?

You cannot advance to other levels without passing earlier levels. The pace of this app is excruciatingly slow. The C is always present on the keyboard, which is not real life and I would like the option to turn it off.

Developer Response ,

Hi! Sorry to hear you have problems with the app.

Please ensure that your Do Not Disturb hardware switch is off to be able to hear sound in the app. Please review the video and "How to identify an interval?" section in the wikipedia of the major second to get an answer to your question. E to F is not a major second for example.

As for advancing to higher levels more quickly, you actually can. And it was also explained in the app intro. Either click on the key-icon in the purple menu that comes up when opening a lesson to a subject to go to a lesson which will unlock gold immediately if passed. Or scroll down until you find a subject you think is the right level and click on the nearest lock-icon to go to a lesson which will unlock everything until there if passed.

I hope to have answered your questions.

Sound not working

The ideas are great, it’s just the sound doesn’t play back sometimes. Sometimes I only hear one note when it’s asking for intervals, and sometimes notes just don’t play. If sound worked consistently, it’d be really good.
