Ellos lo definen así: "This is a quality in the sound that makes all the Cs sound similar. The chroma of the C is the same across all the Cs in all the octaves. Focus on this third point every time you answer a question."
Pero no logro entender qué es. Y en la segunda lección, en las instrucciones, me dicen esto: "Listen for the difference in chroma between the C, D and the E and identify their names. Do NOT try to judge the distance between them. This means do NOT focus on their relationship (i.e. the highness or lowness compared to each other). Rather, focus on the chroma that they present uniquely to your mind's ear."
Así que a ver si alguien podría decirme qué significa esta palabra!! Gracias y saludos
