A unique musical instrument. An interactive music theory medium. An amazing solmization machine. A universal MIDI tool. All in one: "MIDI SolFa Mode-Go-Round" unites and extends the possibilities of the apps "Musk MIDI Keyboard", "Musk MIDI Player", "Musk Diatonic Modes" and the "SolFa Mode-Go-Round". Therefore there are many creative and didactic use cases. Play and grasp music! Use cases: ========== * Play on the diatonic or chromatic keyboard. * Study or teach scales, church modes, and the circle of fifths. * Discover improvising polyphonic canons. * Learn Movable-Do and Fixed-Do solmization. * Connect to your MIDI apps and devices or play with connected "SolFa Mode-Go-Rounds". * Load sounds and polyphonic pieces. * Tune into your part. Hear its solmization. Touch instruments: ================== * The app features a diatonically oriented spiral shaped keyboard with 7 keys per octave. (Tone circle) * With it you can easily play well sounding melodies and chords in major, minor or other church modes. + Besides it, there is a chromatic piano keyboard. (iPhone: Landscape orientation, iPad: double tap piano-button) Sounds: ======= * Instrumental sounds: a General-MIDI sound font is pre-installed. (See also "Musk MIDI Keyboard" for more options.) * To study church modes and solmization, the syllables "do re mi fa so la ti" where recorded in 3 octaves. + Freely mix instrument and solmization sounds. Listen to the solmization of the tenor, hear the bass as piano and the soprano as flute notes. + Choose a small choir ("Erlebnisland") with warm sounds or synthetic Bruno, who really sings to the point. Music theory: ============= * The generalised touch circle of fifth gives access to 12 tonics und 7 modes. * The touch instruments change according to the selected tonic and mode. * There are 5 mathematical-musical base modulations. * Interactive tutorials introduce you to the operation. * Get a fine feeling for the character differences between the diatonic scales Major (Ionian), natural Minor (Aeolean) and the church modes Dorian, Phrygian, Lydian, Mixolydian and Locrian. * Understand how they are interrelated. + Improvise up to five-part counterpoint canons "note-by-note": You play the melody and the canon assistent shows how to proceed. * You can also invent normal canons. Just play in half notes. + You can change labels on the tone circle, e.g. to test your or your students knowledge. Solmization: ============ * The syllables depend on the pitch, the chosen tonic/mode configuration and the solmization method. * They are shown on the tone circle and can be heared. * Solmization methods: absolute solmization (Fixed-Do), relative solmization (Movable-Do) and scale degree solmization. MIDI features: ============== * With this app, you can send and receive MIDI notes and play back MIDI files. * All features of "Musk MIDI Keyboard" and "Musk MIDI Player" are available. (See "Related Apps" in the App Store) + Record tracks and export midi files. + During recording of notes, the related solmization syllables can be attached to the track as lyrics. These can be shown by any MIDI-Karaoke player. + This app sends and receives configuration change commands. You can keep all connected "MIDI SolFa Mode-Go-Rounds" in sync. + You can also add bass notes with an external notation app. These will trigger tonic/mode changes. Synchronization: ================= + Notes and configuration changes are transmitted via MIDI to connected devices and apps. + Using SharePlay you can play with friends over the Internet and play back midi files synchronously. + Nearby devices, e.g. in the classroom, can synchronize their settings via OSC and OSC-Query.
