O Círculo de Quintas transforma a teoria musical em algo que você vê, toca e ouve. • Disco interativo: escolha o tom ou gire o disco e veja na hora os acordes do campo harmônico — tônica, subdominante, dominante, relativas menores e sensível. • Mapa funcional: entenda o papel de cada acorde na música — o que descansa, o que levanta e o que pede resolução. • Cifras: digitações para violão, viola caipira (cebolão em Mi) e piano, da mais simples à mais avançada, com áudio. • Cadências: progressões prontas em qualquer tom, como pop de 4 acordes, ii–V–I, I–IV–V e plagal. • Com sétimas: veja e ouça os acordes com a 7ª em todas as abas. • Tabela: o campo harmônico dos 12 tons em uma só tela. • Imprimir: gere em A4, em escala real, o disco e a máscara para montar em papel. Feito para iPhone e iPad, em retrato ou paisagem. Funciona sem internet, sem cadastro e sem anúncios.
