音乐(Music)是大多数人喜爱的东西。因此，通过动手实验使其成为一种有趣的学习体验将鼓励您玩押韵、声音和旋律。
谷歌于 2016 年创建了Chrome 音乐实验室( Chrome Music Lab)( CML )。它是一个简单易用的在线资源，供学生和音乐教师使用。(CML)
编码人员和音乐家使用可免费访问的工具一起使用Chrome和网络音频(web audio)，这些工具可让您使用代码来创建声音。
Chrome 音乐实验室的目标是让访问者能够可视化和触摸声音以了解声音的样子、了解旋律的工作原理、创建节奏并将绘画转化为音乐。
CML 网站(CML website)有一些称为实验的部分，可以让任何年龄的人探索音乐的工作原理。每个实验都有不同的重点( Each experiment has a different focus)，如钢琴卷(piano roll)、歌曲制作(song maker)、谐波、语音微调器(voice spinner)和声波。
Chrome 音乐实验室是如何工作的？(How Does Chrome Music Lab Work?)
Chrome Music Lab是一款直观直接的音乐软件(music software)。明亮多彩的功能使其对所有年龄段的人都平易近人且友好。
CML 共享开源代码(open-source code)，因此音乐家和编码人员可以构建自己的实验。跨设备的任何人都(Anyone)可以立即打开它并开始播放，而无需等待应用程序下载和安装。
任何人探索音乐越容易，每个人的好奇心、创造力和灵感就越有吸引力。许多(Many)实验只能在现场立即使用。这意味着您将无法下载、导出或共享您的作品。
其中两个实验允许您共享、嵌入和下载您的创作。这两个实验是Song Maker 和 Melody Maker(Song Maker and Melody Maker)。
如何使用 Chrome 音乐实验室创建旋律(How To Create a Melody Using Chrome Music Lab)
首先访问 CML 网站( CML website)并单击Melody Maker选项卡。您可以通过将光标放在块内来查看每个实验的名称。
旋律制作器(Melody maker)有一个简单的界面。只需(Simply)单击不同的框。每个盒子都有不同的注释。尝试单击几个框，然后点击播放(Play)来聆听您的旋律。
方块越低，声音越低。要更改速度，请将蓝色球(blue ball)向左移动以使其变慢。
将蓝色球(blue ball)向右 移动，使音乐更快。(music faster)
玩弄这些盒子，直到你创造出你喜欢的东西。单击(Click)声音将其删除。下面的旋律是(melody below)一闪一闪小星星(Twinkle Twinkle Little Star)的第一部分。
播放(play button)按钮旁边的橙色按钮(orange button)会重复您创建的旋律。
如何使用 Chrome 音乐实验室歌曲制作工具(How To Use Chrome Music Lab Song Maker)
Chrome Music Lab Song Maker是最广泛的项目，您可以使用许多不同的选项。
默认屏幕(default screen)有两个八度。与 Melody Maker一样，您可以单击颜色编码的框来听到与每个框相关的音符。
每两个方框中的粗蓝线代表一拍。交替(Alternating)的灰色和白色部分表示音乐小节。
单击底部的Marimba 图标会将声音更改为不同的乐器。(Marimba icon)
额外的旋律乐器(melody instrument)选项是钢琴、弦乐、木管乐器和合成器。
要擦除或删除笔记，请单击它。如果您想一次删除多个，请按住鼠标按钮并拖动您要删除的注释。
或者您可以使用右下角的撤消按钮。(Undo)
使用Song Maker，您可以一次演奏多个音符，使其听起来像和弦。
使用屏幕底部的块选项卡来更改节奏声音。选项有 conga、electronic、block 和 kit。
通过移动底部的蓝色球来改变速度或节奏。(speed or tempo)
尝试不同的选项以选择您最喜欢的选项。您还可以使用麦克风图标(microphone icon)来录制您的声音或您想要添加的任何其他声音。
完成歌曲创作后，单击右下角的“保存(Save)”按钮。您将看到一个弹出窗口，显示查看您的歌曲的链接( link to view your song)。
或者您可以将您的歌曲分享到Facebook 和 Twitter(Facebook and Twitter) ，复制嵌入代码以放在网页上或下载(page or download)Midi 或 Wav 文件(Midi or Wav file)。
如何创建和弦与和弦(How To Create Harmony & Chords)
如果您的画布上有东西并且您想开始另一个项目，请单击屏幕右上角的重新启动(right-hand corner)。(Restart)
让我们从按住鼠标两拍开始，然后按下面的屏幕截图向上缩放。
通过添加块来创建三分之二的和谐(Create harmony)，如下面的屏幕截图所示。我们在下面的块 2、3、4 和 5 中添加了两个节拍，显示了三分之二的间隔。听这里的和谐(Listen to the harmony here)。
现在让我们从Chrome 音乐实验室(Chrome Music Lab)的和声中创建和弦。添加第五个间隔以创建下面屏幕截图中的每个和弦。
听听这里的和弦是怎样的(Listen to how the chords sound here)。
如何使用 Chrome 音乐实验室振荡器发出酷炫的声音(How To Make Cool Sounds With Chrome Music Lab Oscillators)
首先转到CML 主页(CML homepage)并单击 Oscillators。
振荡器通过以特定频率以稳定速率振动来发出声音。通过向上或向下拖动小部件来更改(Change)频率。使用箭头更改振荡器的类型。
https://musiclab.chromeexperiments.com/Oscillators/尝试一下。上下移动振荡器并聆听它们发出的声音。
频谱图有什么作用？(What Does Spectrogram Do?)
使用Spectrogram(Spectrogram)在彩色图片中查看构成声音的频率。
比较不同声音的频谱图。(Spectrograms)从屏幕底部选择乐器或声源 开始。(Start)
下图(image below)显示了竖琴产生的频率的直观表示。
您还可以使用麦克风录制自己的声音或在屏幕上绘制以创建抽象的时髦声音。
开始使用 Chrome 音乐实验室制作音乐和声音(Start Making Music & Sounds With Chrome Music Lab)
您(Are)准备好开始使用Chrome 音乐实验室(Chrome Music Lab)，看看您可以创作什么样的声音和音乐了吗？上手很简单。前往CML 网站( CML website)并尝试一些实验。
Chrome Music Lab: How To Make Cool Music & Sounds
Music is something most people love. So, making it a fun learning expеrience through hands-on experiments will encourage playing with rhyme, sound, and melody.
Google created Chrome Music Lab (CML) in 2016. It is a simple to use online resource for students and music teachers.
Coders and musicians came together working with Chrome and web audio using freely accessible tools that let you use code to create sound.
The Chrome Music Lab’s goal is to enable visitors to visualize and touch sound to see what sound looks like, learn how melody works, create rhythms, and turn drawings into music.
The CML website has sections called experiments that enable anyone at any age to explore how music works. Each experiment has a different focus, such as piano roll, song maker, harmonics, voice spinner, and sound waves.
How Does Chrome Music Lab Work?
Chrome Music Lab is intuitive and straightforward music software. The bright and colorful features make it approachable and friendly to people of all ages.
CML shares open-source code so musicians and coders can build their own experiments. Anyone across devices can instantly open it up and start playing without waiting for an app to download and install.
The easier it is for anyone to explore music, the more compelling it is for everyone to be curious, creative, and inspired. Many of the experiments can only be used immediately and on the spot. This means that you won’t be able to download, export, or share your work.
Two of the experiments do allow you to share, embed, and download your creations. Those two experiments are Song Maker and Melody Maker.
How To Create a Melody Using Chrome Music Lab
Start by going to the CML website and clicking on the Melody Maker tab. You can see the name of each experiment by putting your cursor inside the block.
Melody maker has a simple interface. Simply click on different boxes. Each box makes a different note. Try clicking a few boxes and then hit Play to hear your melody.
The lower the block, the lower the sound. To change the speed, move the blue ball to the left to make it slower.
Make the music faster by moving the blue ball to the right.
Play around with the boxes until you create something you like. Click on a sound to delete it. The melody below is the first part of Twinkle Twinkle Little Star.
The orange button next to the play button repeats the melody you created.
How To Use Chrome Music Lab Song Maker
The Chrome Music Lab Song Maker is the most extensive project with many different options you can use.
The default screen has two octaves. Like Melody Maker, you click on the color-coded boxes to hear the notes associated with each box.
The heavy blue lines every two boxes represent one beat. Alternating gray and white sections indicate music measures.
Clicking the Marimba icon at the bottom will change the sound to a different instrument.
The additional melody instrument options are piano, strings, woodwind, and synth.
To erase or delete a note, click on it. If you want to delete several at a time, hold the mouse button down and drag over the notes you want to remove.
Or you can use the Undo button on the bottom right-hand side.
With Song Maker, you can play multiple notes at once making it sound like a chord.
Use the blocks tab on the bottom of the screen to change the rhythm sounds. The options are conga, electronic, blocks, and kit.
Change the speed or tempo by moving the blue ball on the bottom.
Try the different options to choose the one you like best. You can also use the microphone icon to record your voice or any other sound you want to add.
When you have finished creating your song, click the Save button in the lower-right corner. You will see a popup showing the link to view your song.
Or you can share your song to Facebook and Twitter, copy the embed code to put on a web page or download a Midi or Wav file.
How To Create Harmony & Chords
If there is something on your canvas and you want to start another project, click Restart in the top right-hand corner of the screen.
Let’s start by holding down the mouse for two-beats and go up the scale as in the screenshot below.
Create harmony in thirds by adding the blocks as seen in the screenshot below. We have added two beats in blocks 2, 3, 4, and 5 below showing intervals of thirds. Listen to the harmony here.
Now let’s create chords from the harmony in Chrome Music Lab. Add a fifth interval to create each of the chords in the screenshot below.
Listen to how the chords sound here.
How To Make Cool Sounds With Chrome Music Lab Oscillators
Start by going to the CML homepage and clicking on Oscillators.
Oscillators make sound by vibrating at a specific frequency at a steady rate. Change frequencies by dragging the widget up or down. Use the arrows to change the type of oscillator.
Try it out, by goingo to https://musiclab.chromeexperiments.com/Oscillators/. Move the oscillators up and down and listen to the sounds they make.
What Does Spectrogram Do?
See the frequencies that make up sound in a colorful picture with Spectrogram.
Compare the Spectrograms of different sounds. Start with choosing an instrument or sound source from the bottom part of the screen.
The image below shows a visual representation of the frequencies produced by a harp.
You can also use the microphone to record your own sounds or draw on the screen to create abstract funky sounds.
