I have analysed the use of portamenti by violinists Janine Jansen, Itzhak Perlman, Jascha Heifetz and Nathan Milstein in the first 8 bars and the two parallel phrases of the Max Bruch Violin Concerto No. 1 in G minor. I have copied their portamenti and recorded myself performing theese phrases in style of each violinist. By doing this I have learnt new ways to use shifting on the violin for expressive purposes and realized how much there is to learn by imitating your predecessor..
