Quinterval is an interactive circle of fifths including the display of the corresponding scales. A key in the circle can be selected either by touching the tonic or by turning the slider in the middle. The circle displays both the respective major and parallel minor scales. The display ranges from F-flat major (D-flat minor) to G-sharp major (E-sharp minor). A second slider can be used to move the visible circle section accordingly. The note names can be set between german, english or italian notation. The lower area shows the related major scale with its key signature. The first step and the sixth step with the corresponding minor scale are highlighted. The notes can be displayed with G-Clef, C-Clef or F-Clef. The accidentals can also be displayed before the individual notes. Additional functionality is available as an InApp purchase: - Display the notes of the parallel minor scale - Display triads with their chord names - Playback notes by tapping on them

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
