Jazz Improvisation Advisor for the Improviser
It has also been used for transcription. Because rhythm-section (e.g. piano, bass, drums) accompaniment is automatically generated from chords, Impro-Visor can be used as a play-along device. Now having a wider array of accompaniment styles, its use is not limited to jazz.
- Lead sheets and solos can be constructed through either point-and-click or using a plain text editor (one is provided, but any editor can be used).
- Optional automatic note coloration shows whether notes are consonant or dissonant with chords and scales.
- Harmonic note entry option guides the user to select notes that are consonant with harmony. Similarly, transposition options provide chromatic or harmonic transposition.
- Solos or solo fragments can be played back immediately on the computer, with automatic rhythm section accompaniment.
- Can be used for self-study, classroom, or play-along. Any segment of a leadsheet can be played back in looped mode.
- Users can define new accompaniment styles. There is spreadsheet-like Style Editor, and a Style Extractor facility that helps create styles from MIDI performances. .
- Solos may be exported as MIDI files, with accompaniment if desired.
- It is not necessary that the soloist memorize the solos that are created in Impro-Visor. The act of constructing solos is intended to help one get a better understanding of the tune and of solo construction. But one can use some or all of the ideas from pre-constructed solos, as many generations of outstanding players have done.
- Impro-Visor also provides a way for the user to create and save licks for later use. Lick creation is helpful in understanding how to construct interesting lines over chord changes.
- When used for transcription, Impro-Visor allows easy _mining_ of selected licks from a solo for future reference.
- Impro-Visor uses menus to help one choose notes, cells, idioms, licks, and quotes for use in constructing a solo.
- Musical knowledge about chords, scales, licks, etc. are definable by the user or instructor, in the form of a vocabulary text file. These items are defined in a single key, and Impro-Visor will transpose them to any key.
- Impro-Visor includes a powerful lick generation capability. Licks, or entire choruses, can be generated in near-real time just by pressing a button. The generation of licks is controlled by a user-modifiable grammar, so that a range of styles and complexities is possible.
- Impro-Visor can learn grammars for a particular style from a corpus of solos.
- Impro-Visor saves solos and other lead sheets as free-form text. We call this leadsheet notation. Although a point-and-click interface is provided, users can optionally enter chords and/or melody in this notation with a standard text editor and have them displayed as a lead sheet in Impro-Visor. The documentation tells how to create and interpret the notation. The notation also provides slash-chords and polychords.
- Any number of leadsheet windows can be open simultaneously. The user can cut and paste melody and chords from one window to another.
- The release of Impro-Visor comes with a few leadsheets with melodies, a number of sample solos, transcriptions, and The Imaginary Book: a large set (over 2500) of chords-only lead sheets for standard, jazz, and some pop tunes.
