0d. Four voice choral

Version 1.3 of the App (and higher) allows you to load and interactively play Midi-files.

If you are singing in a choir, for example, you may study your own part with with the help of solmization syllables.

The demo video shows you how to regulate the instrument and solmization velocity of the individual channels.

This allows you to listen to your part with solmisation while the other voices appear with a neutral instrumental sound.

Later you may mute this channel and practice your part while playing it on the SolFa Mode-Go-Round and/or singing along with the remaining voices.

The score shows a 4-voice setting of Psalm 31 by Heinrich Schütz. The video illustrates the interactive solmisation of the first two choral lines (bars 1-3 and bars 4-6).

The main mode is F-Ionian. The Soprano may stay within this mode throughout. The only little exception is the leading tone B-natural relative to C at the cadence in bar 6. The App will be "reluctant" to solmisate this note in F-Ionian, but you may solmisate the nota ficta with the syllable "fi".

The other three voices (alto, tenor and bass) need to accomodate with the note Eb in bar 5. Tenor and Bass may solmisate the entire second line (bars 4 - 6) in the F-Mixolydian mode. The Alto may only switch after bar 4, as there is still an E-natural to be sung. It is an interesting feature of this second line that the mode moves flatward, while the cadential degree moves a fifth up (from F to C), which is the "sharpward" direction of the line of fifths.
