The first consideration when buying a flute, is  'don't be in a hurry'. If the new flute you are trying is better than the one  you are used to playing, you will be impressed immediately. The simple fact  that the new one has all the pads seating nicely and your old one has a few  small leaks can make a huge difference. You need time to get past the "new  flute fever" so you can make a non-emotional decision. 
      Second, compare if at all possible. Try and get  several flutes even of the same make. This is not always possible with high  priced hand made instruments, but do try. Each flute has a distinctive  personality and sound(s). 
      Third, find several sets of educated ears to  help. Play the flutes in as many acoustical conditions as possible (dead as  well as live rooms). How well does the flute project? 
      Fourth, this is going to be your's flute. It is  not your teacher's flute, or your friend's flute, or your parent's flute. It  must be one that makes you happy. We all have different tastes in tone colour.  The flute must suit you. That said younger players and those fairly new to the  instrument would do well to accept guidance from those teachers and  professionals that they trust. 
      Try to make sure you have all the features you  wish decided before you visit a reputable, knowledgeable flute retailer. 
      1) What is your price range? 
      2) Do you wish a split E mechanism? 
      3) What metal would you like your flute to be  made of? 
      4) Do you wish the tube to be solid or seamed? 
      5) Do you wish an offset or in-line G? 
      6) Do you wish open or closed holes? 
      7) Do you wish soldered or drawn tone-holes? 
      8) Do you wish a B foot-joint? 
      9) What kind of lip plate would you prefer? 
      10) Do you wish a different head-joint? 
      When all is said and done, there are two  important things to consider when buying a flute. The flute has a body and a  head-joint. You must be able to evaluate each part or else you may  inadvertently discard a good flute with a bad head-joint or vice versa. 
      Contrary to popular belief a flute is not always  made from one piece of tube. (I.e. the body and head-joint are made from the  same drawn tube) This is possibly the case with some hand-made instruments but  not usually with the non hand-made flutes. 
      So the advice is simple. A tin head will add  brilliance and vibrancy to the upper middle and top registers where the all  silver combination goes dead and where it is hard to make it sing. A silver  head on a tin flute will add more weight to the sound and reduce the thinness  of the 3rd register. 
      If you find the flute to be appraised has: 
      (1) A good response, i.e. articulation on low  notes. 
      (2) A wide dynamic range 
      (3) A wide range of colours in the sound as you  pass between registers 
      (4) A good flexibility changing between  registers 
      You have not found a good flute...but a  fantastic head-joint!! 
      The head-joint has the biggest effect on the  sound. Factors affecting the sound include the workmanship of the head-joint  and the material it is made of. Consider a solid silver head-joint, especially  if you are purchasing a mass produced flute. However, a handmade silver plated  head can be superior to a solid silver mass produced head-joint. It may be more  expensive. 
      Want to learn more about what Headjoint is  suitable for you? 
      All the above factors are determined by the  manner in which the head-joint embouchure hole has been cutand the parabolic  curve of the mandrel upon which the head was drawn. This latter element has a  great influence on tuning and how the harmonics behave. If the embouchure hole  has not been cut in exactly the right place on the tube then the octaves will  suffer and so forth further up the harmonic series. Measure the dimensions of  the embouchure hole. As a guide something around 10.2/3mm X 11.8/12mm  with a chimney height of 5mm is  good. 
      YOU NEED SOME EXPERTISE TO EVALUATE THESE LATTER  POINTS. 
      A solid silver body is more durable than a  plated body, but doesn’t necessarily improve the sound.  
      The most important contribution of the body is  that of scale.... whether the tone holes are in the correct place for the pitch  you intend to play the flute at. There isn't any point in buying a Flute  pitched at 442 if the people you play with pitch at 440. You will have to pull  the head-joint way out to make an A at the right pitch and will probably  succeed in making all the Left Hand notes too flat. Similarly if you buy a  flute at 440 and try to play at 442 you will push in and succeed in making most  of the Left Hand notes too sharp and as these act as vents for the 3rd register  notes which are 3rd harmonics (D3-G#3) all your upper notes will be also be too  sharp. 
      THIS IS PROBABLY THE MOST COMMON CAUSE OF  SHARPNESS IN THE 3rd REGISTER. 
      It is not difficult to check the scale of a  flute within itself by cross-referencing notes and their alternative harmonics. 
      DON'T USE A TUNER FOR ANYTHING OTHER THAN FOR  SOUNDING A FUNDAMENTAL AND MATCHING PITCHES OF 3rds AND 4ths USING DIFFERENCE  TONES. 
      Try to establish the octave length of the flute  by playing low C and sounding the C2 as a harmonic. Check with fingered C2 and  pull out the head-joint until these are the same pitch. 
        THIS IS  THE MOST IMPORTANT THING TO DO. 
      As a simple test, try a slow A major scale and  listen to each interval carefully. Is the 3rd degree flat enough? A major third  is flatter in the equally tempered scale. What about the 2nd? Try A to B. Then  add C#. 
      Today, flutes are padded well and generally very  well engineered which was not always the case. It might also be good to check  the diameter of the body tube as flutes are made in 3 different thicknesses.  Most hand-made silver flutes are .014 inch but some are .016. This latter fact  is endorsed by his flutes having drawn tone-holes...another factor to consider  as it means you will never have leaks due to rotting solder. The soldered tone  holes add a little weight to the flute, which is countered by the lighter tube.  
      I would say that .016 is best with drawn  tone-holes and .014 best with soldered. Avoid the "commercial"  models, which are drawn tone-holes but .018 tubes. They are not really flexible  enough for a serious student. They really aren't bad flutes just different. 
      Mass, density, and hardness are believed to  correlate positively with sound quality. In general, the denser the metal of  the flute tube, the darker the sound will be. Precious metals are used in flute  making because they are dense, attractive, and easily formed. Powell, for  example,  has a wide selection of  precious metals for flutes. 
      Silver, which has a density of 10.5 has been  used in flute making for 120 years. When properly worked it is capable of  producing its renowned fine tone and excellent response.  
      Powell has developed a patented technology for  combining precious metals in layers. This metal is called Aurumite. Aurumite  consists of a flute tube where 14k rose gold (which is denser and harder than  sterling silver)  is placed on the inside  of the tube and fused to an outer layer of sterling silver. The sound quality  of Aurumite has much of the darkness of gold while preserving the resonance and  projection of sterling silver. 
    Gold is denser than silver and, when alloyed with  other metals, is also harder. Gold flutes are prized for their warm tonal  colour and great dynamic range.  |
