***** Highly addictive piano game. ***** A fun way to develop a better musical ear! Great for experienced musicians and beginners. Music students love this app. ---- Interval Ear Training can help improve: • Interval recognition • Sense of pitch • Transcription skills • Improvising skills • Self esteem --- How to Play: • Tap "play" to hear the interval • To hear the interval again, tap "replay" • Use the piano to play the interval yourself • Play often to improve your score! --- MIDI In – Plug in your MIDI keyboard to enhance the experience! (Core MIDI compatible) MIDI Out – If you have a music instrument app (such as a synth) that can run in "background mode" and accepts virtual Core MIDI, you can play Interval Ear Training using the sounds of that app. --- Tips for the Beginners: Use the + and - keyboard range control to set the keyboard to a small range such as "C, D" or "C, D, E". Keep practicing, and as you progress you'll want to make the range larger. --- Tips for the Pros: Set "Feedback" to "Never" and turn on "Autoplay" to play continuously without ever missing a beat. Crank up the tempo to see how fast you can go! For more advanced ear training features, you'll want to Unlock Pro Settings. --- Interval Settings: Tempo – 60 to 320 BPM Keyboard Range – Starting at 2 notes in a major scale (ex. “C, D”) and up to 12 notes in a major scale (ex. “C, D, E, F, G, A, B, C, D, E, F, G”) with the ability to change octaves. Feedback – Set to "Never" to stop all messages. Set to "Wrong" if you only want messages for incorrect intervals. Sound – Set to "Piano" to hear the built-in piano sound. Set to "MIDI Out" to hear the sound of a music instrument app (such as a synth) that can run in "background mode" and accepts virtual Core MIDI. Autoplay – Turn on to always play the next interval immediately. Turn off if you want to play the keyboard freely between intervals. Key Labels – Turn off to remove note names on white keys. Allow Unison – Turn off if you don't want the same note to be played twice in a row. --- Pro Settings (requires in-app purchase): Scale – 13 major scales Difficulty - Diatonic, Random Tonic, Chromatic Length – 2 to 6 notes --- About the Difficulty Setting: "Diatonic" uses notes from a major scale. This setting is recommended. "Random Tonic" uses notes from a random major scale each time. "Chromatic" mode is the "extreme mode" where any combination of notes is possible. As a result, strange intervals like the Augmented 2nd (ex. F to G#) are possible. --- About the Score: Interval Ear Training is all about self progression. Tap the score to reset at any time. The game goes on forever and the music never ends! --- Can you guess the next note? Download the app to find out!

Read full descriptionHide full description
A guitar practice app that draws the relationship between chords and scales on the neck itself. ■ The whole neck, drawn Chord tones, scale tones, extensions and avoid notes, muted and open strings — each told apart by colour and shape. Switch to degrees and a shape becomes the same shape in every key. ■ Every fingering a chord has From the chord book anyone learns first to every position on every run of adjacent strings. Choose by which string the root is on, and narrow it down by arrangement: close, drop 2, drop 3, shell, power chord. ■ Progressions written in degrees Diatonic or not, a progression is built from degrees. Change the key and the whole thing transposes; change key part way through and it modulates. Start from a preset or from nothing at all. ■ Arpeggios with a rhythm of their own Not only up and down: three-finger and Travis-style patterns that have a rhythm in them, and a different pattern for each bar if you want one. ■ Eight recorded instruments Electric, acoustic and nylon-string guitar, piano, organ, harp, cello and flute — each note pitch-corrected one at a time. A synthesised string is there too. ■ More than thirty scales Every mode of the major and minor scales, pentatonics, both blues scales, bebop, whole tone, diminished, altered, Hungarian minor, and the Japanese scales: hirajoshi, in sen, yo and ryukyu. ■ It all stays on your device No account, no sign-in. Settings and saved progressions live on the device only, and nothing about what you play is sent anywhere. On a tablet the neck stays visible while you work; on a phone it stays pinned while the controls scroll under it. ―――――――――― ZZZ FretHarmony Pro (auto-renewing subscription) - Length and price: 1 year / ¥360 - What it does: hides every advert and removes the limit on saved progressions - Renews every year unless cancelled at least 24 hours before the period ends - Cancel any time in your App Store account settings; cancelling takes effect at the end of the period already paid for Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://smolt-stage.com/home/privacy/zzz-fretharmony-privacy-policy-ios-en.html
