Using a very slow tempo can help convey deep and painful emotions in music, as seen in Schumann's Opus 124, which is originally intended to be played at a fast tempo.

Different dynamics, such as playing loudly versus softly, can significantly alter the emotional impact of a piece, making it feel more temperamental or calming.

When performing, it's essential to determine what you want to express and adjust the tempo accordingly to fit that idea.

The speed of attack on the strings affects the legato feeling; a slower approach is gentler and helps maintain a smooth sound, while a faster approach can be more aggressive.

I think the tempo of writing can influence how ideas spread and resonate with audiences.

Different tempos, dynamics, and tone colors are essential tools for musical expression.

Passages in music are meant to take us from point A to point B, and practicing them slowly can hinder speed despite improving tone production.

Adding elements like vibrato and rubato can infuse personality into the melody, making it more expressive and engaging for the listener.

Phrasing is essential when playing a passage, and I personally enjoy incorporating phrasing into my performance. When playing fast scalar passages, focus on the overall crescendo rather than each individual note, as the first note should not be accented but rather serve as the beginning of a crescendo leading to the theme.
