Read full description

The highest rated and most comprehensive fingering guide available for Violin, Viola, Cello and Double Bass (Simandl and Rabbath positions). Includes double stops! Decide which hand position would be best for the interval or passage. Instantly switch between written note and piano key at the touch of a button. Support for Key Signatures to more easily find a fingering in the music you're working on. • Hand Positions: 15 positions on the Violin, 15 positions on the Viola, 16 positions on the Cello, and 12 Simandl positions or 6 Rabbath positions on the Double Bass. • Display "beginner tape" on the fingerboard as well as string names and colors. • Notate one or two notes in Treble, Alto, Tenor or Bass clef. How to Use: Pick a written note (touch the staff) and have the fingering displayed and concert pitch played. Touch a button and reveal the note on the piano. Play a concert pitch on the piano, and have that pitch's fingering displayed. Touch a button and reveal the transposed note written on the staff. Written and concert pitches are the same for all but the double bass, which transposes, sounding an octave below what is written. • Use the ‘Play' button to repeatedly hear the note or interval being displayed. Selecting a Pitch: Using the Staff (transposed for the current instrument): Simply touch and slide up and down on the staff to select the note, slide to the right or left of the note for sharps and flats. Using the Piano (concert pitch): drag in the area below the keyboard to move the keyboard, touch to play notes, touch & slide to change the pitch. When you glissando up the keyboard, notes will be notated as a raised value (sharps), when you glissando down, notes will be notated as lowered values (flats). Use the up and down arrows to move chromatically up and down without touching the music staff or piano keyboard.
