Fingering Strings for iPhone is the highest rated and most comprehensive fingering guide available for violin, viola, cello, and double bass. This app is a must-have for musicians of all levels, providing detailed hand positions for each instrument. With 15 positions for the violin, 15 positions for the viola, 16 positions for the cello, and 12 Simandl positions or 6 Rabbath positions for the double bass, users can easily navigate through different hand positions to find the best fingerings for any interval or passage.

The app offers a user-friendly interface, displaying the fingerboard with "beginner tape" markings, string names, and colors. It also allows users to notate one or two notes in treble, alto, tenor, or bass clef. Switching between written notes and piano keys is effortless with just a touch of a button.

To use the app, simply pick a written note on the staff to see the corresponding fingering and hear the concert pitch. Alternatively, users can play a concert pitch on the piano and have the app display the corresponding fingering. The app also includes a "Play" button to repeatedly hear the displayed note or interval.

Selecting a pitch is intuitive, with options to use the staff or the piano. On the staff, users can touch and slide up and down to select a note, and slide to the right or left for sharps and flats. On the piano, users can drag in the area below the keyboard to move the keyboard, touch to play notes, and touch and slide to change the pitch. The app even notates raised values (sharps) when glissandoing up the keyboard and lowered values (flats) when glissandoing down.

Fingering Strings for iPhone is an invaluable tool for musicians, providing a comprehensive fingering guide with a user-friendly interface. Whether you're a beginner or an advanced player, this app will enhance your playing and help you find the perfect fingerings for your instrument.
