As a teacher of music at a conservatory, I must have vasted hours writing simple and complex arrangements using the more wellknown apps,- I´m sure other teachers and musicians know what I mean,- when I could have been able to do the job quicker and easier with Pizzicato. I don´t see the necessity of going into details, but this app do everything you need - and it is intutive and it does i well. And for 15 usd it´s a real bargain! It´s highly recommended!
