Double Bass,String Bass Solo - Digital Download SKU: A0.1075710 Composed by Ottakar Sevcik. Arranged by Evan Halloin. Classical. Individual part. 27 pages. Evan Halloin #679892. Published by Evan Halloin (A0.1075710). Otakar Sevcik's Op. 3 Variations are arranged here for double bass. I've changed the keys in many variations to lie well on the bass, and even arranged a few variations in multiple keys in order to work on different registers of the instrument. All the articulations remain exactly as Sevcik wrote them. This will give you plenty to work on!
