These exercises are brilliant for practising double-stopped sixths! Use them for intonation work, and to develop a really solid left hand technique!
Hook, Line, & Sinker is a great study to use for practising hooked bowing. We use this technique to avoid unwanted accents or using too much bow when playing uneven note values. (such as dotted rhythms) in order to avoid unwanted accents on the shorter notes and to stop us from running out of bow!
