B-flat major and E-flat major

Why are B-flat major and E-flat major the most common keys in music for brass and woodwinds?

 

  • Why is music for brass instruments and woodwinds usually written in flat keys such as B-flat major and E-flat major and sometime F-major? Does it have something to do with the instrument itself?

    i play a Bb clarinet, so i understand what you mean. these 2, sometimes 3, scales, are the least complex. for the clarinet & trumpet, the Bb major scale has no flats or sharps. the Eb major has 1 flat on B, and the F major has 1 sharp on F. these scales are easy to play and not hard to learn

    B-flat major and E-flat major

    when you start putting 3 or 4 sharps in there, it gets real hard to play actual music. that’s why the music is written in the B, E, and F major scales so frequently. :]

  • I’ve noticed that a lot of energy vitamins have B vitamins or niacin instead of caffeine. Do these give the same effect as caffeine, or am I better off buying a pack of vitamins with caffeine?
    Answer by Jared
    B Vitamins are co-factors for cellular energy. That is they are essential for us to turn our food intake into ATP (our energy within the cell).

    Caffeine is a CNS stimulant. It directly stimulates the nervous system and rather quickly. It has nothing to do with energy production.

    Niacin is a B-vitamin, it is B-3.

    Unless you are deficient in B Vitamins, they will have no effect on you. It is more hype or marketing gimmicks with the 1000+ % of B-vitamins. The effect you feel off energy supplements is the Caffeine, Sugar, and some of the other directly stimulatory CNS ingredients. It isn’t the B-Vitmains.

    You would be better off going with just Caffeine, but B-Vitamins are cheap to manufacture so it surely doesn’t hurt you to take them in excess. Your body will excrete whatever it doesn’t need in the urine.

    Take care,

  • A and B have a race on a circular track of 510 meters.A who runs faster meets with B in the middle of the 5th round.
    Now in a 3 kM race how much start A must give B so that the race ends dead heat, i.e. A and B reach the goal at the same time.
    Answer by kuiperbelt2003
    what do you mean by the fifth round, do you mean the fifth lap?

    I am interpreting your question to mean that A completes 4.5 laps when B completes 3.5 laps. This means that A travels 45/35 or 9/7 faster than B.

    Thus, we can write the distance equations for A and B as:

    A must travel x+3 km in the same time as B travels x km; A travels at 9/7v and B travels at v, so:

    x+3=9/7 vt
    3=vt =>t=3/v

    substitute this expression for t into the first equation and get:

    x+3=9/7v*(3/v)=27/7
    x=27/7-3=6/7 km

    A must start 6/7 km farther back; or A must travel 9/7 farther than B to finish at the same time, and 9/7x 3 = 3 6/7 km
