Understanding harmony is an essential skill for any musician. Harmony is the springboard that elevates melodies to their full emotional potential.

Harmony Cloud™ is a revolutionary step forward in the world of ear training created by world renowned jazz vibraphonist and music educator Stefon Harris, and software entrepreneur and jazz trombonist Clif Swiggett. It is designed to help all musicians, from beginner to professional, expand their ears, deepen their understanding of harmony, and fearlessly explore the world of improvisation. Its underlying (patent-pending) algorithm stitches together chords you select into an unending source of unpredictable, yet musical, chord progressions.

"Listen and Play" lets you immerse yourself in chord progressions and play along with your instrument (or voice). Use it to deepen your intuitive sense of harmony, to practice improvisation, to play by ear, and to improve aspects of your performance including intonation and emotional expressiveness.

"Bass Note Practice" teaches you to identify the pitch of the bass note and recognize bass line movements. Bass lines are the foundation of every chord progression and the more accurately and quickly you can hear the bass note, the better.

"Chord Quality Practice" deepens your emotional and physical connection to chord qualities including major, minor, diminished, augmented, and sus4. You will learn to recognize these qualities intuitively and reflexively.

"Inversions Practice" teaches you to hear the difference between root, first, and second inversions. Inversions are chord voicings that put the tonic, the third, or the fifth of the chord in the bass note. Each inversion is very distinct, beautiful, and has different harmonic tendencies.

"Full Chord Practice" lets you combine three essential skills (recognizing bass note, chord quality, and inversion) to fully identify chords quickly, accurately, and completely by ear.

"Play Chord Pitches" develops your ability to identify each of the distinct notes in a chord. When a new chord plays, use the keyboard to identify each of its pitches.

"Take the Challenge" to test your skill level, go for high scores, and track your progress. Each of the challenges tests one of the essential skills that you've practiced. When you start a challenge, like a musical performance, there’s no stopping, pausing, or restarting midway through. Every challenge is scored. Your scores, as well as other performance stats, are saved so that you can see your progress over time.

Harmony Cloud can be tailored to any musician's or teacher’s needs. Chord progressions can range from very simple I, IV, V progressions to progressions that include hundreds of chords. This makes it easy to learn and grow at your own pace. You have control of all aspects of the music including tempo, volume, sounds, key signature, and much more.

We invite all musicians to install Harmony Cloud. And be sure to visit the Harmony Cloud YouTube channel for instruction and inspiration.

While the other apps and methods for learning may be something we all do as a big part of our practice routines, I believe they lack what this app provides. We tend to think and see our way through our practice routine more than hear. This app definitely puts all the intervals in to a musical context that challenges your ear. I love it, can't stop using it. You can stop reading now, because that's all you really need to hear. I honestly believe this app will change the way you experience music. As a result your musical conversation will be based on a different part of your brain, the part that will make all the difference in your playing. After using this app guided by someone who knows it, I experienced a paradigm shift. I think the only analogy I can use is when one learns another language. They speak it roughly and slowly translating from their language to the language spoken. Once they stop translating and start thinking in that language it flows and they speak much easier. Base your conversation from where it comes from and stop translating!


Great app for ear training!!

My college professor recommended I download this app for ear training, and it has definitely been a great help! It's become easier to anticipate hoed changes when I play in real time. The app is very user friendly and everything is easily accessible. There's only one thing I could think of as an improvement to make an already great app even better, and that is to add 7th chords as well as extensions! I really hope more musicians who take their training seriously download this app and share it with others, especially jazz musicians who need a helping hand with hearing chord qualities and changes.

Worth Every Penny (and more)!!!

You NEED this app! I have a degree in music, and it still takes me to school. It has improved my ear training skills immensely. I have used it with my private students aged 6 and up and everyone learns something from it. Don’t sleep on how useful this app can be. If that doesn’t convince you to grab it, you know you have spent more money on way less useful things. Put your money towards something extremely helpful and beneficial (like this app)!!!
