| One bowed lyre was the Welsh crwth, which by the 13th century had gained a fingerboard running from the crossbar to the soundbox. |
| The instrument, itself is at least as large as its modern counterpart, the soundbox appears to be larger than that of the present day guitar. |
| Originally, the soundbox of the charango was made from the shell of an armadillo, which gave it a unique sound and appearance. |
| The double psaltery had two ranks of strings, one on either side of the soundbox. |
| This change affected the soundbox of the instrument, its straight sides now giving way to slight curves. |
