Professor Sherman Violin Academy
Lesson 4: Go Tell Aunt Rhody / 《罗迪阿姨》

中文说明
这一课要稳定、像唱歌一样。慢速温暖乐句可用全弓；流动音符用上半弓更清楚；快速练习可用四分之一弓；下半弓训练力量和音色。左手手型要自然，按弦要有信心，避免手指无力或过度僵硬。

练习步骤
1. 演奏前先确定慢而稳定的速度。
2. 练习换弓，不要出现突出的重音或卡顿。
3. 主旋律歌唱线条可用全弓，速度加快时减少用弓长度。
4. 逐音检查左手按指和音准。
5. 把每个乐句当成一句话，有开始、发展和结束。

作业
每天15分钟：节拍器慢练、平稳换弓、音准检查、乐句情感处理。

English Notes
This lesson should be steady and song-like. Use full bow for slow, warm phrases; upper-half bow for clearer moving notes; quarter bow for faster practice; and lower half to develop strength and tone. Keep the left-hand finger shape natural, press with confidence, and avoid both weak fingers and stiff fingers.

Practice Steps
1. Set a slow, even tempo before playing.
2. Practice bow changes without accent bumps.
3. Use full bow for the main singing line, then reduce bow length as the tempo increases.
4. Check finger placement and intonation one note at a time.
5. Shape each phrase as a sentence with beginning, middle, and ending.

Homework
Daily 15 minutes: slow tempo with metronome, smooth bow changes, intonation check, phrase shaping.

第1至5课共同技术重点：
- 用弓：短节奏用上半弓；快速小音符用四分之一弓；下半弓练力量与控制；慢速歌唱性乐句用全弓。
- 左手：手指保持自然，不塌指，不硬直。指尖下指要有力量，大拇指放松，认真听音准。
- 情感：不要只拉对音，要像唱歌一样处理乐句，按照视频示范加入音乐表情。

Core technique for Lessons 1–5:
- Bow use: upper half for clean short rhythms; quarter bow for fast small notes; lower half for strength and control; full bow for slow, singing phrases.
- Left hand: natural finger shape, not collapsed and not over-straight. Drop the fingertip with energy, keep the thumb relaxed, and listen for accurate intonation.
- Expression: do not only play correct notes. Sing the phrase, shape the line, and add feeling from the video demonstration.
