Getting Started with MusicLM Access
Since MusicLM is currently in an experimental beta phase, access must be requested through Google‘s sign-up waitlist. Once your spot is confirmed, you can begin interacting with the tool via the AI Test Kitchen site. Here is a walkthrough of the full access process:
Join the Waitlist
Start by visiting the MusicLM waitlist page and entering your Google Account email address. This submits a request for access that will be processed over time as additional capacity becomes available. Given high demand, it may take days or weeks depending on volume. But joining sooner rather than later gives the best chance at early access.
Look Out for Your Invite Email
Once your request has been approved, you’ll receive an email direct from Google with an invitation link to activate your MusicLM access. The timing of this invite depends on where you are in the waitlist queue. If anxious, checking your updates tab is worthwhile as is ensuring Google emails aren‘t incorrectly filtered as spam.
Accept the Terms of Service
Upon clicking the invitation link, you‘ll be redirected to the MusicLM onboarding flow on the AI Test Kitchen site. The first step is reviewing and accepting Google‘s Terms of Service, which outline appropriate ethical usage of the tool. This includes limiting commercial applications and avoiding copyright infringement.
Configure Your Access Permissions
Next, you‘ll be presented with permission screens to confirm what data MusicLM can access. This generally includes profile information like your Google Account name and avatar. Granting access here enables a personalized MusicLM experience.
Craft and Submit Your First Prompt!
With setup complete, you‘ll at last see MusicLM‘s primary user interface for submitting text prompts and generating musical compositions! We‘ll explore detailed guidance in the next sections. But as a quick test, try inputting a simple phrase like "cheerful melody in a fast tempo" and watch MusicLM work its magic!
Crafting Effective Prompts
The prompts you provide are crucial for guiding MusicLM to produce compelling compositions. As such, putting some thought into properly structuring your text can make quite a difference in the end result. Follow these tips when formulating prompts:
Specify Descriptors Like Genre, Tempo, Instruments
Details like the desired genre, tempo, instruments, mood, musical style, etc. help MusicLM dial into what you‘re looking for. Sentences like "upbeat indie rock song with energetic drums and guitar" perform better than vague descriptions.
Use Multiple Sentences For Extra Context
Supplementing your initial descriptor with additional sentences providing further musical direction often yields improved results. For example, extending the previous prompt to say: "Upbeat indie rock song with energetic drums and guitar. Make the melody lighthearted and fun to dance to. Focus on driving percussion and rhythmic basslines."
Describe The Listening Experience
Rather than purely technical music terms, explanatory phrases can also be effective. Sentences like "It‘s a sunny Saturday morning and this is the perfect feel-good track for my weekend playlist" paint a picture of the desired listening experience.
Strike a Balance With Length
While extra context helps, giant paragraphs are overkill. Try to keep prompts between 1-5 sentences or 50-100 words. This conciseness forces you to prioritize key details.
Don‘t Worry About Song Structure
Describing desired verse/chorus patterns, specific chords/melodies, or complex song sections makes prompts overly rigid. MusicLM works best when given creative freedom. Focus prompts on mood, genre, instruments, and listening experience.
Now that you know how to form effective prompts, let‘s look at actually generating music with MusicLM.
Generating and Exploring Your AI-Created Music
Once submitted, MusicLM requires some time to work its magic transforming text prompts to musical compositions. Here‘s an overview of what to expect during generation and playback:
Wait For Processing
Expect around 10 seconds of processing after you hit the generate button. A loading spinner will indicate MusicLM is working. More complex prompts can take slightly longer.
View Two Musical Options
For each prompt, MusicLM will provide two 30-second musical samples with differing interpretations. The dual options showcase its creative flexibility and let you choose your favorite.
Scan The Score Preview
Helpfully, MusicLM also supplies a preview of the musical score to accompany each sample. Perusing the notes and arrangement corresponding to what you hear provides useful insight.
Listen and Compare
With generation complete, take a moment to listen to both options and determine which is most aligned with your original vision. Pay attention to how effectively the samples capture the desired mood, genre, tempo and more.
Give Feedback via Trophies
Once you‘ve selected your preferred composition, provide feedback to MusicLM by awarding it a virtual trophy 🏆. This feedback loop helps refine future results by highlighting what resonated most.
Iterate and Improve
If neither sample quite hits the mark, don‘t be afraid to revisit your prompt and enhance it with more descriptive guidance. Part of the fun with MusicLM is an iterative process of refinement. Tweaking prompts and comparing results is key to unlocking its potential.
Now that you’re familiar with the end-to-end generation flow, let’s examine some power user functionality.
Advanced Features and Functionalities
While MusicLM’s core functionality is straightforward, Google has packed in some nice quality of life features expanding its flexibility. Take advantage of these to level up your creative guidance.

Expert Tips and Tricks
If you really want to unlock MusicLM’s capabilities, incorporate these pro tips into your creative process:
Reference Multiple Genres and Artists
While MusicLM can’t precisely emulate songs from specific musicians, naming comparable genres, bands, or composers can help steer results. Prompts like “Fast-paced punk rock in the style of Green Day” or “Dreamy ambient chillout á la Brian Eno” work well by citing musical touchpoints.
Get Granular with Descriptors
Beyond high-level genres and moods, include as much descriptive detail as possible calling out preferred instruments, tempo ranges in BPM, types of melodic patterns, comparable key signatures, etc. Music theory terminology can be quite powerful for honing MusicLM’s compositions.
Describe Imagined Environments
As highlighted previously, avoid overspecifying rigid song structures or chord progressions since MusicLM needs creative leeway. Instead define prompts by imagining scenarios for how resulting music could be applied. Descriptions like “Background ambience for a Mars colony” or “Menu music for a pixilated retro arcade” work wonderfully.
Iterate Quickly via Remixing
MusicLM also offers a “Remix” feature which regenerates a prior composition with slight parametric variations. When you land on a great foundation sample, remixing introduces productive mutations to build upon without needing to re-describe the full vision.
Troubleshooting Poor Results
If a series of samples seem off: simplify prompts to isolate issues, double check proper genre/mood descriptors were provided, listen closely to identify missing elements, and verify an appropriately broad range of musical characteristics were defined. Prevent overconstraining MusicLM’s creative process if possible.
