Fig 1.
Picture of the test setup including the three cameras, the lifting platform and measuring rod cross (spatial directions are indicated by x, y and z).
The perspective views of each camera are shown with a musician in performing position.
Fig 2.
Pictures of a trumpeter in the side view (upper) and top view (lower) perspective. The origin of the coordinate system was placed at the mouth opening of the instrument player.
Fig 3.
Pictures of a flute player (from left to right) in the side view, top view and front view at the test setup while playing the melody. Three clouds were developed from the flute: at the mouthpiece, at the end of the instrument and from the key plane.
Fig 4.
Diagrams of distances in x-, y- and z-direction (a, b, c) from left to right for the trumpets. The 0 point in the time-scale refers to the end of the task. Each task is represented by a red (upper border) and a black curve (lower border) indicating the maximum distances of the cloud in the respective directions. The median devolution in both directions is shown in green. The corresponding diagrams with color-coded notation of the three tasks are displayed in the S1 Fig.
Fig 5.
Diagrams of distances in x-, y- and z-direction (a, b, c) from left to right for the flutes. The 0 point in the time-scale refers to the end of the task. Each task is represented by a red (upper border) and a black curve (lower border) indicating the maximum distances of the cloud in the respective directions. The median devolution in both directions is shown in green. The corresponding diagrams with color-coded notation of the three tasks are displayed in the S2 Fig.
Fig 6.
Diagrams of distances in x-, y- and z-direction (a, b, c) from left to right for the clarinets. The 0 point in the time-scale refers to the end of the task. Each task is represented by a red (upper border) and a black curve (lower border) indicating the maximum distances of the cloud in the respective directions. The median devolution in both directions is shown in green. The corresponding diagrams with color-coded notation of the three tasks are displayed in the S3 Fig.
