Musiek: strykinstrumente

Strykinstrumente

Aktiwiteit

Om instrumente te identifiseer [lu 2.4, 2.5]

DIE SKILPAAIE

Voltooi eers:

  • Maatslag
  • Tempo
  • Is die instrumenteklank hoog en/of laag?
  • Beskryf wat jy hoor.

Om die skilpaaie uit te beeld, gebruik die komponis strykinstrumente.

Hoe lyk die strykinstrumente?

Kyk na die skets van die skilpaaie. Daar is VIER verskillende strykinstrumente:

Viool

Altviool

Tjello

Kontrabas

Hierdie vier instrumente vorm die strykinstrumente. Strykinstrumente bestaan uit ‘n houtkas en vier snare. Die snare word met ‘n strykstok bespeel.

Strykinstrumente word met groot sorg vervaardig. Al die houtdele word aanmekaar vasgegom en daar word geen spykers of skroewe gebruik nie. Hierdie groep instrumente wissel in grote: Hoe groter die instrument, hoe laer die klank; hoe kleiner die instrument, hoe hoër die klank.

(Vergelyk met groot en klein diere: ‘n muis is klein, sy klank is hoog; ‘n olifant is groot, sy klank is laag.)

Plak prentjies of maak tekeninge van die vier strykinstrumente.

Hoe bring ons klank voort op die strykinstrumente?

Sodra ‘n mens die strykstok oor die snaar stryk, vibreer die snaar. Dit veroorsaak klank! Hoe langer die snaar is, hoe laer is die klank; hoe korter die snaar, hoe hoër is die klank. Om die snare korter of langer te maak, word die linkerhand hoër op of laer af op die snare gedruk.

In plaas van die strykstok te gebruik, kan die snare ook gepluk word met die regterhand. Dit veroorsaak kort klanke.

Die toonhoogte van die strykers:

Viool: hoog

Altviool: redelik hoog

Tjello: redelik laag

Kontrabas: laag

Rangskik die strykinstrumente soos volg:

1. van klein na groot

2. van hoog na laag.

Watter afleiding kan jy maak?

STRYKINSTRUMENTE

1. Klein na groot
2. Hoog na laag
AFLEIDING:

Assessering

LEERUITKOMS 2: REFLEKSIE Die leerder kan krities en skeppend op kuns- en kultuurprosesse, -produkte en -style in vergange, asook huidige kontekste reflekteer.

Assesseringstandaard

Dis duidelik wanneer die leerder:

2.4 maatslae soos vier-vier en drie-vier kan herken;

2.5 na musiekinstrumente luister en hulle kan identifiseer in terme van voorkoms, naam, wyse van klankproduksie, timbre en algemene toonhoogteklassifisering (hoog-laag).

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
