The frame has two panels and multiple supports. Each support is attached between the two panels and has a top surface and a trough. The trough is longitudinally formed in the top surface of the support. The spacer is mounted in the trough of the support and has multiple protruding mounts. Each bar is mounted between two supports and has two through holes. The sleeves are respectively mounted through the through holes of the bars. Each fastener is mounted through the sleeves and in the protruding mounts of the spacers to fasten the bars on the supports of the frame. Therefore, the spacers are not moved during production for improved production consistency. ## Claims ### Claim 1 A xylophone comprising a frame having two panels, each panel having an inner surface and two edges; and two pairs of supports being attached between the two panels and each support having a top surface; and a trough being longitudinally formed in the top surface of the support; multiple spacers being respectively mounted in and corresponding respectively to the troughs of the supports and each spacer having a top surface; a two edges; two sets of bars being mounted respectively on and corresponding respectively to the pairs of the supports and each bar having a top surface; two ends; and two through holes being formed through the top surface of the bar respectively adjacent to the ends; multiple sleeves being respectively mounted through the through holes of the bars; and multiple fasteners being respectively mounted through the sleeves. ### Claim 2 (depends on 1) The xylophone as claimed in claim 1, wherein the trough of each support comprises a groove being formed longitudinally in the top surface of the support and having two sides; and two guide channels being respectively formed in the sides of the groove; and each spacer further has two shoulders being respectively formed on the edges of the spacer and mounted in the guide channels of a corresponding trough. ### Claim 3 (depends on 2) The xylophone as claimed in claim 2, wherein each spacer further has multiple protruding mounts being formed on and protruding from the top surface of the spacer and each protruding mount having a hole formed through the protruding mount. ### Claim 4 (depends on 1) The xylophone as claimed in claim 1, wherein each spacer further has multiple protrusions being formed at intervals on and protruding from the top surface of the spacer. ### Claim 5 (depends on 2) The xylophone as claimed in claim 2, wherein each spacer further has multiple protrusions being formed at intervals on and protruding from the top surface of the spacer. ### Claim 6 (depends on 3) The xylophone as claimed in claim 3, wherein each spacer further has multiple protrusions being formed at intervals on and protruding from the top surface of the spacer. ### Claim 7 (depends on 4) The xylophone as claimed in claim 4, wherein each panel further has multiple seats being mounted on the inner surface of the panel; and each support is mounted in one of the seats of a corresponding one of the panels. ### Claim 8 (depends on 5) The xylophone as claimed in claim 5, wherein each panel further has multiple seats being mounted on the inner surface of the panel; and each supports is mounted in one of the seats of a corresponding one of the panels. ### Claim 9 (depends on 6) The xylophone as claimed in claim 6, wherein each panel further has multiple seats being mounted on the inner surface of the panel; and each support is mounted in one of the seats of a corresponding one of the panels. ### Claim 10 (depends on 7) The xylophone as claimed in claim 7, wherein four seats are implemented on each panel, two being mounted centrally and two being mounted respectively adjacent to the edges of the panel; and the supports are implemented as two primary supports being mounted respectively in the seats mounted centrally on the panels; and two secondary supports being longer than the primary supports and being mounted in the seat mounted adjacent to the edges of the panels; and each bar is mounted between one primary support and one secondary support. ### Claim 11 (depends on 8) The xylophone as claimed in claim 8, wherein four seats are implemented on each panel, two being mounted centrally and two being mounted respectively adjacent to the edges of the panel; and the supports are implemented as two primary supports being mounted respectively in the seats mounted centrally on the panels; and two secondary supports being longer than the primary supports and being mounted in the seat mounted adjacent to the edges of the panels; and each bar is mounted between one primary support and one secondary support. ### Claim 12 (depends on 9) The xylophone as claimed in claim 9, wherein four seats are implemented on each panel, two being mounted centrally and two being mounted respectively adjacent to the edges of the panel; and the supports are implemented as two primary supports being mounted respectively in the seats mounted centrally on the panels; and two secondary supports being longer than the primary supports and being mounted in the seat mounted adjacent to the edges of the panels; and each bar is mounted between one primary support and one secondary support. ### Claim 13 (depends on 10) The xylophone as claimed in claim 10, wherein each bar has two countersinks being formed in the top of the bar and located respectively around the through holes of the bar. ### Claim 14 (depends on 11) The xylophone as claimed in claim 11, wherein each bar has two countersinks being formed in the top of the bar and located respectively around the through holes of the bar. ### Claim 15 (depends on 12) The xylophone as claimed in claim 12, wherein each bar has two countersinks being formed in the top of the bar and mounted respectively around the through holes of the bar.
