JTL大提琴自學第一步 互動式教學系統

I'm Teacher Hu, the owner of Jetlee Musical Instruments Shop, and a professional violin repair technician. This app is for those who want to start on their own without a teacher.

The cello is not a "high-standing violin."

You must play it sitting down, with the body upright between your legs, supported by the tailpiece—this is the biggest difference between it and the violin or viola. The first lesson teaches you how to sit, how to choose a chair, and how high to adjust the tailpiece (the top edge of the body should be approximately at chest height, and the C string tuning peg approximately behind your left ear). Incorrect posture will cause back pain over time, so it's better to spend a few extra minutes adjusting.

The bass clef, with two dots sandwiching Fa. The cello uses the bass clef. The app places it before all the standard sheet music, so you can read the score before playing; the dotted clef also provides a comparison of treble, alto, and bass clefs. It also supports simplified notation: switch between simplified and standard notation at any time.

Follow along and you'll learn!

- Posture, bow holding, tuning, open strings—one lesson at a time, each with a small challenge.

- Normal left-hand fingering (index, middle, ring, and little fingers, each finger separated by only a semitone).

- Automatic sheet music roll-up, metronome with indicator light, demonstration and listening (three tones: cello, piano, and choir).

- Microphone pickup and playing along—the cursor only moves when you're playing correctly.
