I suggest not rushing to put hands together, unless they are eager to try it. Yikes - what about G7? Tell them it is the same as G, for now. (After that makes sense, have them try the chords with fingers 5, 2, & 1 on C, F, or G.) Using the sheet with chord symbols, I have them use their "pointer" finger - left hand! - to play each chord symbol key. I tell students this is like playing a bass guitar part. Probably just a single note in the left hand. What's the easiest way for beginners to start with chords? Perhaps just reading the notes and adding left hand chords in the coming weeks will be accomplishment enough!įinger replacement is actually a difficult and advanced technique, though eventually we hope that it will become second nature to our piano students. it depends on you and what you think is most beneficial at this stage of your student's learning. In their method books, they may not encounter this skill for a while, but in this song, it is easy to understand and imitate, if you take them through the process every week until they GET IT.īut. It's up to you, the teacher, to ingrain the finger replacement technique into your student AT SOME POINT is now the time? Is finger replacement necessary in Twinkle? In spite of the fingering I have placed in the music - the five to four and four to five - your student is most likely to COMPLETELY IGNORE those helpful suggestions and just play "1 - 1 - 5 - 5 - 5 - 5 - 5." or something like that! We can encode 7 7 5 5 4 4 2 as F(7,5,4,2,x) and set it to a variable B so that we can re-use these notes.įinally, we can join the notes like so: join(A,B,B,A) to get the final sequence of notes.Please scroll down the page for the download links. By joining the two resultant lists and storing it in a variable A, we can re-use these 14 notes at the end of the song. Also, the middle 14 notes ( 7 7 5 5 4 4 2, 7 7 5 5 4 4 2) is just 7 7 5 5 4 4 2 repeated twice. With a full understanding of function F, we can now encode the number sequence shown earlier with F.įirst note that the first 14 notes ( 0 0 7 7 9 9 7, 5 5 4 4 2 2 0) are repeated at the end as well. This will play the note d for twice as long, emulating a half note. Public byte Samples, which is a line segment of length 2 at y level d. Samples = Samples.Concat(RenderNote(note + "", note.Length > 1 ? note - '0' : 4, fmt)).ToArray() Var result = new byte // For 120BPM tempoįor (int i = 0 i ().Select(x => x.Value)) Throw new NotImplementedException("Unsupported Note") Private static IEnumerable RenderNote(string note, int length, Fmt fmt) WavFile = header.ToByteArray().Concat(thefile).ToArray() Var thefile = data.SelectMany(x => x.ToByteArray()).ToArray() If (value.GetType().Equals(typeof(byte))) Return ((char) value).Select(y => Convert.ToByte(y)) If (value.GetType().Equals(typeof(char))) Return BitConverter.GetBytes((UInt32) value) If (value.GetType().Equals(typeof (UInt32))) Return BitConverter.GetBytes((UInt16) value) If (value.GetType().Equals(typeof (UInt16))) Return o.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance) Public static byte ToByteArray(this object o) Not wasting too much of my time doing it.wav file from the string used for the QBasic solution in C# (single octave, no accidentals). So, what I did here was implement support for generating a. This is a code-golf, so shortest code wins.The focus should be on code size, sound quality, or both (explain which one you decided on). Preferably, it should sound good as well. At the very least, the song should be easily recognizable. For example, embedding the Ogg Vorbis file from Wikipedia would not be allowed. Your program must actually generate its output. If your programming language doesn't have convenient access to audio hardware, your program must create an output file in some standard format such as WAV or MIDI. Your program must use the computer's sound card. Musical note#Note frequency (in hertz) (the formula for calculating the frequency of each note).Modern musical symbols (to learn about the music notation used above).Twinkle Twinkle Little Star (has an audio clip of what your program's output should sound like).Some Wikipedia articles that may be useful: Attribution: Helix84 at the English language Wikipedia Blahedo at the English language Wikipedia.)
