JTL 中提琴自學第一步 互動式教學系統 讓自學更容易

I'm Teacher Hu, the owner of Jetlee Musical Instruments Shop, and also a violin maker and repair technician.

This app is my method for teaching the viola, made for those who want to start on their own without a teacher.

【The viola is not a larger version of the violin】 The four strings are C, G, D, and A, a fifth lower than the violin; the thickest C string is absent in the violin and is also the most beautiful part of the viola. The first lesson teaches you to distinguish between the two instruments to avoid buying the wrong viola or learning the wrong sheet music.

【Alto clef, starting from Do on the third line】 The viola uses the alto clef. The app places it before all the standard sheet music, allowing you to recognize the score before playing; clicking on the clef provides a comparison of the treble, alto, and bass clefs. It also supports simplified notation: you can switch between simplified notation and standard sheet music at any time, with numbers matching the textbook.

【Teach It By Doing It】
・Hold the violin, hold the bow, tune, open strings – one lesson at a time, each with a small challenge.

・Finger position guide (including the second finger on the C and G strings). Pitch accuracy depends on your ear, finger position on the guide.

・Automatic sheet music roll, metronome with indicator light, demonstration and listening (three timbres: violin/piano/choir).

・Microphone pickup and playing along – only move the cursor when you're playing correctly.

【Music Tracks】
・Introductory Nursery Rhymes: Twinkle Twinkle Little Star, Mary Had a Little Sheep, Ode to Joy, Two Tigers, Silent Night, Christmas Bells, Happy Birthday, Amazing Grace

・Taiwanese Oldies and Classics: Looking Forward to Spring, Rainy Night Flowers, Four Seasons Red, Moonlit Night Sorrow, Congratulations, Farewell, Home Road (Thinking of Hometown), Greensleeves, Danny Boy

・8 Original JETLI Songs: Cradle, Twilight, Riverside, Old Street, Hopscotch, Going to the Market, Rainbow After the Rain, The Way Home. Each piece has a separate card, clearly stating the mood, key techniques, and the reason for the chosen tempo.
