String Quartet Cello,String Quartet - Level 3 - Digital Download SKU: A0.752605 By Ed Sheeran. By Amy Wadge and Ed Sheeran. Arranged by Dury Loveridge. Pop. Score and parts. 8 pages. Dury Loveridge #3453119. Published by Dury Loveridge (A0.752605). Ed Sheeran's massive hit 'Thinking Out Loud' arranged for cello quartet. The first cello part is in tenor clef to help with reading, but goes no higher than the 'b' above the harmonic so is suitable for grade 6/7 players. This remains true to the simplicity of the original song with little added, but is perfect for concerts and school ensembles.
