The study addresses the preparatory information needs of potential performers of solo classical guitar concerti. Identifying a range of specific decisions that play an important part in the pre-performance planning of an anticipated concerto performance provides performance considerations for each selected concerto. The content of six solo classical guitar concerti spanning almost 180 years by six composers from four countries was analysed for the purpose of this study. Two early guitar concerti by guitarist composers Mauro Giuliani (1781-1829) and Ferdinando Carulli (1770-1841), two modern concerti by non-guitarist composers Mario Castelnuovo-Tedesco (1895-1968) and Joaquín Rodrigo (1901-1999) and two modern concerti by guitarist composers Heitor Villa-Lobos (1887-1959) and Leo Brouwer (b.1939) were investigated. The study examines specific compositional and performance aspects of each concerto to serve as a guideline for professional performers, students and teachers. Each concerto was analysed according to similar themes: the historical significance of the investigated concerti, pre-performance considerations, the level of difficulty of selected concerti, technical observations, performance recommendations and observations regarding balance between the soloist and orchestra. As an addendum the study provides a comprehensive list of published concerti for solo classical guitar.
