A fine guitar is easier to choose, play and keep when you understand how it is made. This knowledge base gathers everything we have written about classical guitars: how to choose one, what the woods and constructions do, how to care for an instrument, and the words makers and players use.

Five facts worth remembering

| 52 mm | The standard nut width, which gives room for clean left-hand technique. |
| 45–55% | The relative humidity in which a solid-wood guitar is most comfortable. |
| 8 years | The minimum seasoning time of every piece of wood in an Arrius. |
| 22% | How much more volume our concert constructions allow while keeping the standard dimensions. |
