english: There's a scale paradigm, which is playing a scale up and down, memorized, then there's improvising on a scale, quarter notes, metronome, right hand -- scientifically very safe, but musically really boring.
non_english: Imamo ovde paradigmu skale, što je zapravo sviranje skale gore dole, zapamćeno. I tu je i improvizacija na skali - četvrtine nota, metronom, desna ruka - naučno veoma sigurno, ali muzički jako dosadno.
