| 3D20.10 | sonometer | PIRA 200 | A sounding box with strings, tuning machines, and adjustable bridges. |
| 3D20.10 | sonometer | 3D20.10 | The standard two wire sonometer. |
| 3D20.10 | sonometer | Sj-1 | A long spruce box with three strings, tuning machines, and adjustable bridges. |
| 3D20.10 | sonometer | S-131 | A general discussion of sonometers and the various demonstrations possible. |
| 3D20.11 | vertical sonometer | AJP 58(1),93 | A vertical sonometer allows tension to be applied by simply hanging weights. |
| 3D20.14 | tuning fork driven sonometer | S-4b | Place a tuning fork on the bridge of a tuned sonometer and observe the motion of a small piece of paper placed on the wire at its center. |
| 3D20.15 | harmonics on a string | Sj-3 | Pluck a string at different distances from the end or pluck while touching at various nodes. |
| 3D20.20 | modes of string oscillation on scope | PIRA 1000 | |
| 3D20.20 | modes of string oscillation | Sj-2 | Use voltages generated by magnets placed across steel strings attached to an oscilloscope to view string motion. |
| 3D20.20 | sonometer | Disc 10-02 | An electromagnetic pickup is used to display the waveform of the sonometer string on an oscilloscope. |
| 3D20.21 | guitar and scope | PIRA 1000 | |
| 3D20.21 | guitar and scope | Disc 10-01 | Show the output of an electric guitar on an oscilloscope. |
| 3D20.30 | bowed string | AJP 44(11),1077 | An overhead projector is modified for strobe projection and the string is bowed with a motorized "O" ring. |
| 3D20.30 | sonometer wire motion | S-132 | Demonstrate the motion of a sonometer wire by stroboscopic shadow projection or using a light beam and revolving mirror. |
| 3D20.30 | string in a projector | S-133 | The motion of a string is shown by placing any portion in a lantern projector limited by a slit. The difference in bowing, plucking, and striking can be demonstrated. |
| 3D20.31 | optical detection of string motion | AJP 53(12),1195 | An optical detection system for showing the position of a vibrating string. |
| 3D20.35 | resonance of strings | S-116 | A tuning fork is held against a three string sonometer with one string tuned to the fork frequency. Only the tuned string will vibrate. |
| 3D20.36 | simulated piano string coupling | AJP 52(2),137 | A classroom device that simulates the coupled motion of piano strings and theory of the device. |
| 3D20.45 | longitudinal vibrations in strings | S-108 | Stroke a string attached to a diaphragm across the open end of a cylinder. By jerking, you can make it bark like a dog. |
| 3D20.50 | Aeolian harp | PIRA 1000 | |
| 3D20.52 | aeolian harp | S-141 | Mount strings vertically on a rotating table to give the sound of strings excited by the wind. |
| 3D20.52 | aeolian scope | S-142 | A sort of aeolian stethoscope. |
| 3D20.60 | rubber-band harp | S-134 | The pitch of a rubber-band changes only slightly with great increase in length (tension). |
