iAutoharp vs Negative Harmony

The iAutoharp is easy and fun to play; just tap a chord button and strum to hear that chord played as sweetly as if on the actual 37-string instrument. * Switch keys and chords effortlessly. No musical training is required, and the interface is well designed for the small screen. * Use any of six chord buttons, initially set to common chords so you can easily accompany your singing or play along on most popular tunes. * Reconfigure chord buttons to get any of more than 150 possible chords for each key. You don't need to understand music theory, but if want to learn more about it, the autoharp is a great way to experiment. * Try picking out a melody by "pinching" subsets of strings with two fingers. Please look for other apps by HotPaw Productions in the Music category of the App store: the inTuna Strobe Guitar Tuner, Music Spectrograph, and Sing-inTuna, to visualize if you can sing in tune.

Negative Harmony lets you explore one of music theory's most fascinating transformations: reflecting any chord or progression across a tonal axis to produce its harmonic mirror image. TAP ANY CHORD Select a root and quality on the interactive Circle of Fifths. See the original chord and its negative simultaneously, with voice-leading automatically applied. BUILD PROGRESSIONS Add chords to a progression and play them back — originals or negatives — with smooth voice leading between every chord. Common tones are held, not re-attacked. UNDERSTAND THE THEORY Built-in theory section explains the concept from first principles: the axis, the transformation formula, voice leading, and the history from Hugo Riemann to Jacob Collier. 5 SOUNDS Choose from Rhodes, Strings, Choir, Organ, or Synth Pad — the same high-quality soundfont used by professional music apps. MULTILINGUAL Full support for English, Spanish, French, German, Italian, and Portuguese.
