Pedro de Araujo's "Batalha de No.6 tom" is a keyboard piece in the toccata style, typical of the Portuguese Baroque. It is musically distinctive for its virtuosic display of rapid figuration, arpeggios, and a sense of improvisational freedom.
The main technical challenge is achieving fluid, rapid execution of scales and arpeggios with a strong rhythmic pulse.
Batalha de No.6 tom is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 7.
You should be comfortable at Henle level 5 — meaning you can already play level 4–5 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of Batalha de No.6 tom lasts about 4 minutes.
